Rio +20: Joining the ecological dots 2012-06-17T11:51:46Z But in the earlier stages of space colonization, populations will be smaller rather than larger, and there will be fewer people with whom to mix genes, such that inbreeding will be a significant danger. Migration from Earth: Human Evolution and Space Colonization 2012-06-15T20:15:00.223Z But a new study in plants indicates that it's not just genes that lead to this so-called inbreeding depression; it's also how these genes are switched on and off.

Bedbugs Get Away with Incest 2011-12-07T00:15:00.257Z Schal said that was a surprise, since an animal or insect population with limited diversity will usually build up and then crash, because genetic defects tend to magnify with inbreeding. Researchers say inbred bedbugs can thrive, that single female can lead to infestation 2011-12-07T08:05:06Z But in some insects, such as bedbugs and cockroaches, inbreeding seems to have become a perfectly safe form of .
