The prettiest names for girls s names that are due a comeback. We assessed sperm longevity for every male individually and calculated halftime sperm longevity from these values for each male.

In contrast to the bias checks, we found differences in allele frequency between selected sperm pools throughout the genome Fig. We checked for two possible sources of allele frequency bias.
