Hybrid zones can form from secondary contact. A hybrid zone exists where the ranges of two interbreeding species or diverged intraspecific lineages meet and cross-fertilize. . Hybrid zones can form in situ due to the evolution of a new lineage [1] [page needed] but generally they result from secondary contact of the parental forms after a period of geographic isolation, which allowed their ...
A hybrid zone may appear during secondary contact, meaning there would be an area where the two populations cohabitate and produce hybrids, often arranged in a cline. The width of the zone may vary from tens of meters to several hundred kilometers. A hybrid zone may be stable, or it may not.
Chausie, a hybrid between a jungle cat and domestic cat. Subfamily Pantherinae. Genus Panthera. Ligers and tigons (crosses between a lion and a tiger) and other Panthera hybrids such as the lijagulep. Species P. tigris. A hybrid between a Bengal tiger and a Siberian tiger is an example of an intra-specific hybrid. Family Canidae
This often referred to semi-permeable species boundaries, [19] [163] [164] and examples include e.g. genes involved in olfaction that are introgressed across a Mus musculus and M. domesticus hybrid zone. [165] In hybrid zones with mainly permeable species boundaries, patterns of introgressed regions enable deducing what genomic regions involved ...
In a tension zone there is the increased probability of hybridization between species of the separate zones and thus the tension zone may also be a hybrid zone. [ 6 ] Historically tension zones were entirely natural in origin, however human activity has altered the tension zones in a variety of areas all over the world.
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
For a hybrid form to persist, it must be able to exploit the available resources better than either parent species, which, in most cases, it will have to compete with.For example: while grizzly bears and polar bears may be able to mate and produce offspring, a grizzly–polar bear hybrid is apparently less- suited in either of the parents' ecological niches than the original parent species ...
Hybrid zones are regions where diverged populations meet and interbreed. Hybrid offspring are common in these regions, which are usually created by diverged species coming into secondary contact . Without reinforcement, the two species would have uncontrollable inbreeding .
