Laboratory culturing and selection for increased resistance to cadmium reduce genetic variation in the least killifish, Heterandria formosa.

Environmental toxicology and chemistry - 1 Sept 2007

Athrey N R Giridhar, Leberg Paul L, Klerks Paul L

Abstract excerpt

Populations exposed to environmental contaminants can undergo intense selection pressures, which in turn can lead to a loss of genetic variation. We assessed this loss of genetic variation in the least killifish Heterandria formosa for laboratory populations that had undergone eight generations o...
