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 ...
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
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.
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.
Clines are often cited as evidence of parapatric speciation and numerous examples have been documented to exist in nature; many of which contain hybrid zones. These clinal patterns, however, can also often be explained by allopatric speciation followed by a period of secondary contact—causing difficulty for researchers attempting to determine ...
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 ...
It can occur across hybrid zones due to chance, selection or hybrid zone movement. [8] There is evidence that introgression is a ubiquitous phenomenon in plants and animals, [9] [10] including humans, [11] in which it may have introduced the microcephalin D allele. [12]
Hybrid species are often more vigorous and genetically differed than their ancestors. There are primarily two different forms of hybridization: natural hybridization in an uncontrolled environment, whereas artificial hybridization (or breeding) occurs primarily for the agricultural purposes.
