Introgression is:
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may … See more Introgression or introgressive hybridization is the incorporation (usually via hybridization and backcrossing) of novel genes and/or alleles from one taxon into the gene pool of a second, distinct taxon.
