Question

Crossing over is an ancient adaptation evolved to facilitate the production of diverse offspring genotypes. Ok, let's put some ideas together. We know that meiosis is a complex trait, and we know how it works - each allele copy has an equal chance to be passed on to a gamete. What if, by some mysterious process, a mutation arose that could bias the process of chromosome segregation, so that in a heterozygote, that mutation has a higher than 50% chance of being passed on to the gamete stage. What would be the outcome?
