Difference between interbreeding and sympatry
- (genetics) the act of mixing different species or varieties of animals or plants and thus to produce hybrids
- reproduction by parents of different races (especially by white and non-white persons)
Alan Templeton, a geneticist at Washington University in St. Louis who headed the study reported in Nature, has concluded that yes, there was interbreeding between the different groups.
The potential of disease was an even bigger threat than interbreeding, he said.
These differences in color are sufficient to prevent interbreeding among existing species.
- the occurrence of organisms in overlapping geographical areas, but without interbreeding
Conversely, if genetic exchange occurs between the two lineages in sympatry, interlineage populations should exhibit much less differentiation than should geographically distant NW populations.
This applies globally as well as locally: despite continuous, near-global sympatry between domestic dogs and wolves, hybridization has hardly occurred and only one mtDNA type is shared.
In addition, hosts in sympatry were less likely to reject a mimetic model egg than a non-mimetic one.
