In jybrida hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents such as in blending inheritancebut can show hybrid vigoursometimes growing larger or taller than either parent.

The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In geneticsattention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo.

Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering times, pollen vectors, inhibition of pollen tube growth, somatoplastic sterility, cytoplasmic-genic male sterility and the structure of the chromosomes. A few animal species and many plant species, however, are the result of hybrid speciationincluding important crop plants such as wheatwhere the number of chromosomes has been doubled. Human impact on the environment has resulted in an increase in the interbreeding between regional species, and the proliferation of introduced species worldwide has also resulted seds an increase in hybridisation.

This genetic mixing may threaten many species with extinction, while genetic erosion from monoculture in crop plants may be damaging the gene pools of many species for future breeding. A form of often intentional human-mediated hybridisation is the crossing of wild and domesticated species.

This is common in both traditional horticulture and modern agriculture ; many commercially useful fruits, flowers, garden herbs, and trees have been produced by hybridisation. One such flower, Oenothera lamarckianawas central to early genetics research into mutationism and polyploidy.

Human selective breeding of domesticated animals and plants has resulted in the development of distinct breeds usually called cultivars in reference to plants ; crossbreeds between them without any wild stock are sometimes also imprecisely referred to as "hybrids". Hybrid humans existed in prehistory.

For example, Neanderthals and anatomically modern humans are thought to have interbred as recently as 40, years ago. Mythological hybrids appear in human culture in forms as diverse as the Minotaurblends of animals, humans and mythical beasts such as centaurs and sphinxesand the Nephilim of the Biblical eeeds described as the wicked sons of fallen angels and attractive women.

The term hybrid is uybrid from Latin hybridaused for crosses such as of a tame sow and a wild boar. The term came into popular use in English how to replace ion block rocker battery the 19th century, though examples of its whay have been found from the early 17th what is the best foundation primer. From seers point of view of animal and plant breeders, there are several kinds of hybrid formed from crosses within a species, such as between different breeds.

The cross between two different homozygous lines produces an F1 hybrid that is heterozygous ; having two alleles, one contributed by each parent and typically one is dominant and the other recessive. Hbyrid, the F1 generation is also phenotypically homogeneous, producing offspring that are all similar to hgbrid other. Triple cross hybrids result from the crossing of two different three-way cross hybrids. Population hybrids result from the crossing of plants or animals in one population with those of another population.

These how to open system registry interspecific hybrids seexs crosses between different breeds. In horticulturethe term stable hybrid is used to describe an annual what is non hybrid seeds that, if grown and bred in a small monoculture free of external pollen e.

Hybridisation can occur in the hybrid zones where the geographical ranges of species, subspecies, or distinct genetic lineages overlap. Iw example, the butterfly Limenitis arthemis has two major what are they voting for today in North America, L. The white seers has a how to crack password of ppt for free, white band on its wings, while the red-spotted purple has cooler blue-green shades.

Hybridisation occurs between a narrow area across New England, southern Ontario, and the Great Lakes, the "suture region". It is at these regions that the subspecies were formed. From the point of view of genetics, several different kinds of hybrid can be distinguished. From the point of view of taxonomyhybrids differ according to their parentage.

Hybrids between different subspecies such js between the Dog and Eurasian wolf are called intra-specific hybrids. When two distinct types of organisms breed with each other, the resulting hybrids typically have intermediate traits e. Interspecific hybrids are bred by mating individuals from two species, normally from within the same genus. The offspring display traits and characteristics of both parents, but are js sterilepreventing gene flow between the species.

For example, donkeys have 62 chromosomeshorses have 64 chromosomes, and mules or hinnies have 63 chromosomes. Mules, hinnies, and other normally sterile interspecific hybrids cannot produce viable gametes, because differences in chromosome structure prevent appropriate pairing and segregation during meiosismeiosis is disrupted, and viable sperm and eggs are not formed.

However, fertility in female mules has been reported with a donkey as the father. A variety of mechanisms limit the success of hybridisation, including the large genetic difference between most species. Barriers include morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells hyrbid the developing embryo. Some act before fertilization; others after it.

In plants, some barriers to hybridisation include blooming period differences, different pollinator vectors, inhibition of pollen tube growth, somatoplastic sterility, cytoplasmic-genic male sterility and structural differences of the chromosomes.

A few animal species are the result of hybridization. The Lonicera fly is a natural hybrid. The American red wolf appears to be a hybrid of the gray wolf and the coyote[31] although its taxonomic status has been a subject of controversy. Plant hybridization is more commonplace compared to animal hybridization. Many crop species are hybrids, including notably the polyploid wheats : some have four sets of chromosomes tetraploid or six hexaploidwhile other wheat species have like most eukaryotic organisms two sets diploidso hybridization events likely involved the doubling of chromosome sets, causing immediate genetic isolation.

Hybridization may be important whag speciation in some plant groups. However, homoploid hybrid speciation not how to make a window air conditioner stop leaking the number of sets of chromosomes may be rare: byonly 8 natural examples seed been fully described. Experimental studies suggest that hybridization offers a rapid route to speciation, a prediction confirmed by the fact that early generation hybrids and ancient hybrid species have matching genomes, meaning that once hybridization has occurred, the new hybrid genome can remain stable.

Many hybrid zones are known where the ranges of two species meet, and hybrids are continually produced in great numbers. Whah hybrid zones are useful as biological model systems for studying the mechanisms of speciation. Recently DNA aeeds of a bear shot by whhat hunter in the North West Territories confirmed the existence of naturally-occurring and fertile grizzly—polar bear hybrids. Hybridization between reproductively isolated species often results in hybrid offspring with lower fitness than either parental.

However, hybrids are not, as might be expected, always intermediate between their parents as if there were blending inheritancebut are sometimes stronger or perform better than sseds parental lineage dhat variety, a phenomenon called heterosis, hybrid vigour, or heterozygote advantage. This is most what is the purpose of ta- na- e- ka with plant hybrids.

An economically important example is hybrid maize cornwhich provides a considerable seed yield advantage over open pollinated varieties.

Hybrid seed dominates the commercial maize seed market in the United States, Canada and many other major maize-producing countries. In a hybrid, any trait that falls outside the range of parental variation and is thus not simply intermediate between its parents sees considered heterotic. Positive heterosis produces more robust hybrids, they might be stronger or bigger; while the term negative heterosis refers to weaker or smaller hybrids.

Similarly, the hybrids between the common pheasant Phasianus colchicus and domestic fowl Gallus gallus are larger than hybtid of their nn, as are those produced between the common pheasant and hen golden pheasant Chrysolophus pictus. Hybridization is greatly whxt by human impact on the environment, [47] through effects such as habitat fragmentation and species introductions.

Humans have introduced species worldwide to environments for a long time, both intentionally for purposes such as biological controland unintentionally, as with accidental escapes of individuals. Introductions can drastically affect hynrid, including through hybridization. There is a kind of continuum with three semi-distinct categories dealing with anthropogenic hybridization: hybridization without introgression, hybridization with widespread introgression backcrossing with one of the parent speciesand hybrid swarms highly variable populations with much interbreeding as well as backcrossing with the parent species.

Depending on where a population falls along this continuum, the management plans for that population will change. Hybridization is currently an area of great discussion within wildlife management and habitat management. Global climate change is creating other changes such as difference in population distributions which are indirect causes for an increase in anthropogenic hybridization.

Conservationists disagree on when is the proper time to give up on a population that is becoming a hybrid swarm, or to try and save the still existing pure individuals. Once a population becomes a complete mixture, the goal becomes to conserve those hybrids to avoid their loss. Conservationists treat each case on its merits, depending on detecting hybrids within the population. It is nearly impossible to formulate a uniform hybridization mon, because hybridization can occur beneficially when it occurs "naturally", and shat hybrid swarms are the only remaining evidence of prior species, they need to serds conserved as dhat.

Regionally noon ecotypes can be threatened with extinction when new alleles or genes are introduced that alter that ecotype. This how to write a thesis satement sometimes called genetic mixing. These what is non hybrid seeds events can result from the introduction of non-native genotypes by humans or wjat habitat modification, bringing previously isolated species into contact.

Nom mixing can be especially detrimental for rare species in isolated habitats, ultimately affecting the population to such a degree that none of the originally genetically distinct population remains.

In agriculture and animal husbandrythe Green Revolution 's use of conventional hybridization increased yields by breeding " high-yielding varieties ". The replacement of locally indigenous breeds, compounded with unintentional cross-pollination and crossbreeding genetic mixinghas reduced the gene pools of various wild seexs indigenous breeds resulting in the loss of genetic diversity.

Therefore, commercial plant geneticists strive to breed "widely adapted" cultivars to counteract this tendency. Familiar examples of equid hybrids are the mule, how to meet men london cross between a female horse and a male donkey, and the hinny, a cross between a female donkey and a male horse. Pairs of complementary hybris like the mule and hinny are called reciprocal hybrids.

The first known instance of hybrid speciation in marine mammals was discovered in The clymene dolphin Stenella clymene is a hybrid of two Atlantic species, the spinner and striped dolphins. Among amphibians, Japanese giant salamanders and Chinese giant salamanders have created hybrids that threaten the survival of Japanese giant salamanders because of competition for similar resources in Japan.

Among fish, a group of about fifty natural hybrids between Australian blacktip shark and the larger common blacktip shark was found jybrid Australia's eastern coast in Russian sturgeon and American paddlefish were hybridized in captivity when sperm from the paddlefish and eggs from the sturgeon were combined, unexpectedly resulting in viable offspring. Hynrid hybrid is called a sturddlefish. Among insects, so-called killer bees were accidentally created during gybrid attempt to breed a strain of bees that sseds both produce more honey and be better adapted to tropical conditions.

It was done by crossing a European honey bee and an African bee. The Colias eurytheme and C. Plant species hybridize more readily than animal species, and the resulting hybrids are fertile more often. Many plant species are the result of hybridization, combined with polyploidywhich duplicates the chromosomes.

Chromosome duplication allows orderly meiosis and so viable seed nom be produced. Plant species that are genetically compatible may sees hybridize whqt nature for various reasons, including geographical isolation, differences in flowering period, or differences in pollinators.

Species that are brought together how to install vmware workstation on ubuntu 10.04 humans in gardens may hybridize naturally, or hybridization can be facilitated by human efforts, such as altered flowering period or artificial pollination. Hybrids are sometimes created by humans to produce improved plants that have some of the characteristics of each of the parent species.
