Effects of population size and isolation on heterosis, mean fitness, and inbreeding depression in a perennial plant.

The New phytologist - 1 Oct 2012

Oakley Christopher G, Winn Alice A

Abstract excerpt

• In small isolated populations, genetic drift is expected to increase chance fixation of partly recessive, mildly deleterious mutations, reducing mean fitness and inbreeding depression within populations and increasing heterosis in outcrosses between populations. • We estimated relative effective sizes and migration among populations and compared mean fitness, heterosis, and inbreeding depression for eight large...
