Suppose meiotic drive affects both pollen and ovules and that 80% of the pollen grains and ovules from a heterozygote carry the A allele.
We have seen that meiotic drive (where one allele pushes its way into more than half of the gametes) can lead to deviations from normal proportions of offspring genotypes. Find the probability that an offspring from a selfing heterozygote with genotype Aa has zero, one, or two A alleles. Which cases follow a binomial distribution?
