Species P. tigris. A hybrid between a Bengal tiger and a Siberian tiger is an example of an intra-specific hybrid. Family Canidae. Fertile canid hybrids occur between coyotes, wolves, dingoes, jackals and domestic dogs. Hybrids of unknown fertility can occur between South American foxes of the Lycalopex genus and domestic dogs. Family Mustelidae

Hybridization and introgression, which can happen in natural and hybrid populations, of new genetic material can lead to the replacement of local genotypes if the hybrids are more fit and have breeding advantages over the indigenous ecotype or species. These hybridization events can result from the introduction of non-native genotypes by humans ...
Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare.
Hybridization is considered to be an evolutionary catalyst capable of generating novel genotypes or phenotypes in a single generation. [1] [2] It can also happen with morphologically dissimilar but closely related species (Example: Helianthus giganteus, the giant sunflower).
For example, when trait combinations lead to reduced fitness in the hybrid offspring in specific environments. Genome stabilization - the process by which different ancestry blocks or introgression tracts become fixed within a hybrid species when hybridization between the hybrid taxon and its parent taxa has ceased.
The advantages of species hybridization are 1.) evolution of new interspecific breed, 2.) hybrid vigour, and 3.) enhanced longevity and immunity to diseases (Dubey, A. 2019). Dubey explains each as follows: 1.) A new interspecific breed is due to the mating of two distinguished species. 2.)
Several bird species hybridize with multiple other species. For example, the mallard (Anas platyrhynchos) is known to interbreed with at least 40 different species. The ecological and evolutionary consequences of multispecies hybridization remain to be determined. [2]
