Sentence examples for multiple matings are from inspiring English sources

In populations with five or fewer sex determining alleles, multiple matings are favoured because females that mate more than once may have higher than average fitness [50].

Females should be less willing to re-mate when a single mating is sufficient for maximum egg production than when multiple matings are needed.

Our observations raise the possibility that the echidna is an induced ovulator - in induced ovulators copulation initiates ovulation, and in some species multiple matings are required to initiate ovulation [27].

However, benefits of multiple matings are likely to decline with number of males owing to sampling effects, that is, additional matings will only marginally contribute with genes of better quality [2], unless postcopulatory mate-choice, such as cryptic female choice and sperm competition, is extremely effective [5].

In this non-selfing internal fertilizer, multiple matings are frequent in both sexual functions [ 21].

Results from our study indicated that multiple matings are costly to T. tabaci females in terms of quantitative reproductive output.

While the actual cost for females of multiple matings is unknown, observations on Acilius from the field reveal a very high male harassment rate [35].

Quantifying the cost to females of multiple matings is a challenge for future studies and we tentatively predict that in the natural history of diving beetles, aquatic insects dependent on atmospheric oxygen, lies the key to the extraordinary female counter-adaptations in Acilius and other diving beetles.

One possible explanation for multiple matings is that, although there is no fitness benefit, females may use the sperm from different males to fertilize the eggs which could increase their offspring's genetic diversity (Jennions and Petrie 2000).

For example, if the reproductive pattern I, there is no fitness cost, and the introduced insects are 22 days old, then the thresholds assuming two-occasion mating and unlimited multiple-mating are 48.8% and 43.5%, respectively.

A consequence of female multiple-mating is that ejaculates from different males may overlap in the female's reproductive tract and compete to fertilize her ova (sperm competition; [8]).
