I think this makes sense because eggs are haploid (already only have 23 chromosomes) but a natural next question is: why are eggs haploid if there is a major incentive to pass more of the 46 chromosomes?
If you would say that there are two copies of chromosome 11 in the egg and none in sperm, you would lose sexual selection for chromosome 11.
