As animal populations migrated away from their original sites of domestication, sub-populations were formed through geographic and genetic isolation.
12.
He believed the genetic isolation among Pacific Islanders had produced three separate races which were Micronesian, Polynesian and Melanesian.
13.
However in this case the Mule is usually infertile, and so the genetic isolation of the two parent species is maintained.
14.
Population genetic models can be used to identify which populations show significant genetic isolation from one another, and to reconstruct their history.
15.
When looking at the degree of genetic isolation, they found that intraspecific recombination rate was ~ 50 times higher than the interspecific rate.
16.
Though Northwest Africa has experienced gene flow from the surrounding regions, it has also undergone long periods of genetic isolation in some parts.
17.
A 1991 study suggested that in 75 years of genetic isolation and water scarcity the population had developed physiological mechanisms which improved their ability to conserve water.
18.
Founder effects and the effects of genetic drift are more pronounced for the Icelandic gene pool than other nearby populations, supporting the assumed genetic isolation of the population.
19.
Evidence suggests " D . edule " subsp . " edule " was much more widespread than it is today and became fragmented thus allowing for genetic isolation.
20.
According to the authors, that mixing likely occurred some 600 800 years ago, followed by rapid growth and genetic isolation ( rate per generation 16 53 %; ).
