Testing models of sex ratio evolution in a gynodioecious plant: female frequency covaries with the cost of male fertility restoration.

Evolution; international journal of organic evolution - 1 Feb 2013

Caruso Christina M, Case Andrea L

Abstract excerpt

In many gynodioecious species, cytoplasmic male sterility genes (CMS) and nuclear male fertility restorers (Rf) jointly determine whether a plant is female or hermaphrodite. Equilibrium models of cytonuclear gynodioecy, which describe the effect of natural selection within populations on the sex ratio, predict that the frequency of females in a population will primarily depend on the cost of male fertility...
