In some cases, habitat alterations have resulted in the genetic isolation of dolphin populations.

However in this case the Mule is usually infertile, and so the genetic isolation of the two parent species is maintained.

Also need to be concerned about genetic isolation of populations by dams.

He counted thirty-four local races in the world which were caused by genetic isolation.

They have also resulted in ecological displacement and genetic isolation of R. diazi.

The genetic isolation of the separate subpopulations may present further cause for concern.

This is due to habitat loss, genetic isolation, and conflicts with humans.

Geographical factors can lead to both cultural and genetic isolation from larger human societies.

Moreover, according to geneticists, the most likely explanation for the high frequency of twins is genetic isolation and inbreeding.

Several researchers, however, suggest that their genetic isolation began long before that.
