Genetic pollution leads to homogenization or replacement of local genomes as a result of either a numerical and/or fitness advantage of an introduced species. citation Hybridization and introgression are side-effects of introduction and invasion.
Frequent hybridization and high levels of introgression have caused different species in the same populations to share up to 50% of their genetic information.
These cryptic species lacked evidence of genetic introgression or backcrosses indicating limited fitness for hybrids and effective reproductive isolation and speciation.
This introgression could have provided early dogs living in high latitudes with phenotypic variation beneficial for adaption to a new and challenging environment.
When a population experiences hybridization with substantial introgression, there still exists parent types of each set of individuals.
