Genetic variability and drift load in populations of an aquatic snail.

Evolution; international journal of organic evolution - 1 Apr 2004

Puurtinen Mikael, Knott K Emily, Suonpää Susanna, van Ooik Tapio, Kaitala Veijo

Abstract excerpt

Population genetic theory predicts that in small populations, random genetic drift will fix and accumulate slightly deleterious mutations, resulting in reduced reproductive output. This genetic load due to random drift (i.e., drift load) can increase the extinction risk of small populations. We studied the relationship between genetic variability (indicator of past population size) and reproductive output in...
