Sentence examples for mate choice such from inspiring English sources

His research includes investigating genetic variation in traits related to mate choice such as pathogen disgust and avoidance, mate preferences, and the mental and behavioural aspects of masculinity and femininity.

The MHC loci of vertebrates play a critical role in the immune system but also function in mate choice, such that MHC diversity may be generated by both parasite pressure and disassortative mating (reviewed in [ 80, 81]).

Song and Slatkin (2007) later introduced a flexible graphical method that allowed them to generalize the analysis of Laurie and Weir to cases with more loci and other models of mate choice such as monogamy.

Visual systems are classically thought to show low to no variation across individuals within a species, especially when color vision is modeled in the context of mate choice (such as [ 19, 50– 50]).

The choosiness of both sexes in biparental species results in mutual mate choice such that intrasexual competition for higher quality (larger) mates in both sexes may have contributed to the observed pattern of assortative mating in our species.

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].

Male mate choice under such conditions is consistent with low reproductive rewards of mating with previously mated females.

First, Higashi et al. (1999) considered the possibility that a sudden change in environmental conditions changes the parameters of mate choice in such a way that previously hidden genetic variation of female preferences is suddenly exposed.

Notwithstanding the obvious mating advantage of some males over others in the present experiment, it is necessary to remember that potential mate choice cues, such as territory size and male-male interaction, were not available to the females in our experiment.

Furthermore, indirect and direct mate choice can interact, such that a female's set of potential partners is reduced even before she is ready to mate.

Accordingly, mate choice based on such indicator traits has a clear directionality, making it difficult to conceive how sexual selection could lead to the divergence of preferences between two nascent species.
