In a population the offspring produced tend to be 60% female and 40% male. This bias in sex ratio was investigated and it was found that an allele of a gene in the Y chromosome caused sperm that carried this allele to be less effective at fertilizing eggs. This led to sperm that carried Y chromosomes to be slightly less effective at fertilization compared to sperm cells with the X chromosome, explaining the uneven sex ratio.This is an example of:a. Good genes modelb. Meiotic drivec. Reinforcementd. Genetic hitchhikinge. Pre-zygotic barrier to speciation
