Population genetics of modifiers of meiotic drive 4: Evolution of sex-ratio distortion

A model for the evolution of the sex-ratio meiotic drive system in Drosophila is proposed and analyzed. The model incorporates drive and altered fertility genetic modification The condition change in the sex-ratio of the modifying distortion overcome any relative of meiotic in the carriers of the modified sex-ratio chromosomes. that a sex-ratio modifying chromosome increase is that the relative fertility chromosome. When no fertility model predicts that any increase in distortion differences are involved, of the sex ratio will be favored. loss in carriers the
