Problem:
Question: How and why did Fair Meiosis evolve?
I can hardly think that it provided a fitness advantage to the individual carrying the mutation. Why would it?
Question: Did it evolve through lineage selection?
Question: Was it some kind of pre-existing characteristic of meiosis that have no energy cost and therefore never disappear?
I call fair meiosis the process of meiosis in which each chromosome has an equal chance of transmission.
Question: Is there any selection pressure in favour of alleles causing a fair meiosis? If yes, why? It doesn't seem to me to provide any advantage to the individual carrying this allele.
Give reasoning with your answer.
