Deletion of the entire Acp62F coding region.
Wild-type females mated to homozygous males do not show any significant difference in remating frequency 24 hours postmating relative to females mated to control males.
The total number of eggs and progeny produced by females mated singly to homozygous males does not differ significantly from those produced by females mated singly to control males. No difference is seen either across all 9 days of the assay or for any single day within the 9 days.
Acp62F is not essential for "offense" components of sperm competitive ability; when females are first mated to a wild-type male and then mated to a homozygous male, the homozygous males father 80% of the progeny, similar to what is seen if the second mating is to a second wild-type male (78% of the progeny are fathered by the second wild-type male in this case).
Sperm from homozygous males is able to resist displacement significantly better than sperm from wild-type males; when females are first mated to a homozygous male and then mated to a wild-type male, the homozygous males from the first mating father close to 70% of the progeny (only 39% of progeny are fathered by the first mating father when females are first mated to a wild-type male and then mated to a second wild-type male).
The average number of sperm stored in the seminal receptacles of females mated to homozygous males does not differ significantly from those in females mated to control males.
There is no significant difference in survival, age-specific fecundity or fertility of females mated to homozygous males compared to females mated to control males.
