Overdominant maintenance of diversity in the sea star Pisaster ochraceus.

Journal of evolutionary biology - 1 Jan 2009

Pankey M S, Wares J P

Abstract excerpt

When individuals have higher evolutionary fitness because of being heterozygous at a given gene region, it is known as overdominance. Although overdominant selection could represent an important mechanism for maintaining genetic variation within species, the prevalence of this mode of selection appears to be relatively low. Identification of cases of true single-locus heterozygote advantage are thus useful...
