In the event that she spends sperm off each other boys, up coming she’ll create a combined brood that features both nuts-types of and you may dark-eyed children opublikowano Maj 6, 2022
Most D. recens females remate within a few days and use the sperm of multiple males to sire their offspring. We found that the proportion of females that produced both wild-type and dark-eyed offspring, indicative of multiple mating, increased with the number of days the flies were held together ( ? 5 2 = 27 , p < 0.0001), and that this was owing to a lower number of multiply mated females in the 1-day treatment (? 2 = 20, p < 0.0001; figure 3; electronic supplementary material, figure S7). Whether the wild-type eyed males in the cage were ST or SR did not affect this pattern ( ? 6 2 = 10 , p = 0.13). Using the occurrence of mixed broods is a conservative estimate of remating rate, as we cannot detect when females mate with males of the same eye colour genotype or mate twice but do not use the sperm of both malesbining SR and ST cages within each day, when flies are kept together for 24 h, 20% of females produced mixed broods, indicating they mated with both dark and wild-type males. This suggests that about 40% of females mated at least twice within 24 h, because we only detected half of the broods produced from double matings (95% CI 0.32–0.47). 66% mated at least twice) and increased to approximately 50% after 3 days, suggesting that all of the females had mated twice (figure 3).
When the a woman mates double and every mating is with good random male, half committed she’d be anticipated so you’re able to spouse with one another black and you will wild-form of males (and you will 50 % of enough time she would mate with a few wild-variety of or several black-eyed males)
Profile step 3. Paternity analyses regarding the sperm battle cage experiment mean girls lover proliferate. Revealed is the fraction of women one delivered each other ebony and wild-type of offspring, demonstrating they’d mated with one another kind of boys, broke up by number of days the newest flies occurred along with her additionally the male tester genotype (SR or ST). The fresh mistake bars imply new 95% binomial trust interval. (On line version inside the the color.)
Such studies also provide information about how ladies explore jizz. If the people one to companion more than double utilize the sperm of those men similarly, then extremely otherwise every females is fundamentally sire mixed broods. (więcej…)
