Abstract:
The diploid genotypes of males are widely thought to determine sperm phenotypes, yet
recent work shows that the haploid genetics of the individual sperm cell also contributes significantly.
We tested seven sperm phenotypes, flagellar length and six behaviors, looking for
correlations between genetic and phenotypic variability. While flagellar length appears to be
controlled by the diploid genotype of the source, variation in three of the behavioral phenotypes,
linearity, wobble, and progression are significantly correlated with the heterozygosity
of the male producer. Because males that are more genetically variable produce a sperm
set that is more diverse in its haploid genotypes, we suggest that the correlations may reflect
significant haploid genetic control of sperm swimming behaviors.
