Source: Webster's dictionaryGenetic 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. Source: Internet
Frequent hybridization and high levels of introgression have caused different species in the same populations to share up to 50% of their genetic information. Source: Internet
These cryptic species lacked evidence of genetic introgression or backcrosses indicating limited fitness for hybrids and effective reproductive isolation and speciation. Source: Internet
This introgression could have provided early dogs living in high latitudes with phenotypic variation beneficial for adaption to a new and challenging environment. Source: Internet
When a population experiences hybridization with substantial introgression, there still exists parent types of each set of individuals. Source: Internet
