hybridization between a cattle and human schistosome species.
But hybrid zones imply much more through introgressive
hybridization where hybrids backcross with parental species (Arnold 1997).
Recent studies confirm the old idea introduced by Anderson in the 1940 s in his monograph introgressive
hybridisation , namely that hybridisation can provide a bridge for the genetic exchange of adaptations (genes that increase fitness).
hybridization is well known in plants (Anderson, 1953).
hybridization in Mexican populations of Acacia macracantha and Acacia pennatula (Fabaceae, Mimosaceae).
HYBRIDIZATION AND THE EVOLUTION OF NORTH AMERICAN BAMBOOS AS REVEALED BY NUCLEAR AND CHLOROPLAST DNA.
Limited realized dispersal and introgressive
hybridization influence genetic structure and conservation strategies for brown rockfish Sebastes auriculatus.
hybridization may lead to the occurrence of a hybrid swarm (continuous gradient of individuals from one species via all classes of hybrids to another species), raising questions as to the species' identity (Coyne & Orr, 2004; Price, 2008).
Speciation via introgressive
hybridization in East African cichlids.
The primary concern is that GM varieties could displace native varieties and possibly cause introgressive
hybridization with the wild relatives of maize, such as teosinte, which would forever alter the gene pool.
