Suppose meiotic drive affects the pollen only and that 80% of the pollen grains from a heterozygote carry the A allele. Ovules are normal, and 50% of them carry the A allele. What fraction of offspring from a selfing heterozygote will be heterozygous?
One force that can alter the ratio of heterozygotes produced by a selfing heterozygote is meiotic drive. This means that one allele, say A, pushes its way into more than half of the gametes (ovules or pollen).
