Low worldwide genetic diversity in the killer whale (Orcinus orca): implications for demographic history.

Proceedings. Biological sciences - 22 Jul 2002

Abstract excerpt

A low level of genetic variation in mammalian populations where the census population size is relatively large has been attributed to various factors, such as a naturally small effective population size, historical bottlenecks and social behaviour. The killer whale (Orcinus orca) is an abundant, highly social species with reduced genetic variation. We find no consistent geographical pattern of global diversity...
