Drosophila melanogaster females commonly mate with multiple males
establishing the opportunity for pre- and postcopulatory sexual selection.
Traits impacting sexual selection can be affected by a complex interplay
of the genotypes of the competing males, the genotype of the female, and
compatibilities between the males and females. We scored males from 96 2nd
and 94 3rd chromosome substitution lines for traits affecting reproductive
success when mated with females from 3 different genetic backgrounds. The
traits included male-induced female refractoriness, male remating ability,
the proportion of offspring sired under competitive conditions and
male-induced female fecundity. We observed significant effects of male
line, female genetic background, and strong male by female interactions.
Some males appeared to be “generalists” and performed consistently across
the different females; other males appeared to be “specialists” and
performed very well with a particular female and poorly with others.
“Specialist” males did not, however, prefer to court those females with
whom they had the highest reproductive fitness. Using 143 polymorphisms in
male reproductive genes, we mapped several genes that had consistent
effects across the different females including a derived, high fitness
allele in Acp26Aa that may be the target of adaptive evolution. We also
identified a polymorphism upstream of PebII that may interact with the
female genetic background to affect male-induced refractoriness to
remating. These results suggest that natural variation in PebII might
contribute to the observed male–female interactions.
