Question

Why meiosis in a cell of genotype aa yields a gametes and a gametes in roughly equal numbers why meiosis in a cell of genotype aabb yields gametes of genotype ab and genotype ab in roughly the same proportion why meiosis in a cell of genotype aa yields a gametes and a gametes, but no aa gametes why meiosis in a cell of genotype aabb cannot yield ab gametes?

Answer 1

This is because meiosis can only happen by crossing to genotypes.
