Mate choice for genetic compatibility in the house mouse
In house mice, genetic compatibility is influenced by the t haplotype, a driving selfish genetic element with a recessive lethal allele, imposing fundamental costs on mate choice decisions. Here, we evaluate the cost of genetic incompatibility and its implication for mate choice in a wild house mice population. In laboratory reared mice, we detected no fertility (number of embryos) or fecundity...
متن کاملGenetic and socioeconomic study of mate choice in Latinos reveals novel assortment patterns.
Nonrandom mating in human populations has important implications for genetics and medicine as well as for economics and sociology. In this study, we performed an integrative analysis of a large cohort of Mexican and Puerto Rican couples using detailed socioeconomic attributes and genotypes. We found that in ethnically homogeneous Latino communities, partners are significantly more similar in th...
متن کاملRed and white Chinook salmon: genetic divergence and mate choice.
Chinook salmon (Oncorhynchus tshawytscha) exhibit extreme differences in coloration of skin, eggs and flesh due to genetic polymorphisms affecting carotenoid deposition, where colour can range from white to bright red. A sympatric population of red and white Chinook salmon occurs in the Quesnel River, British Columbia, where frequencies of each phenotype are relatively equal. In our study, we e...
متن کاملMate choice
If you are interested in the diversity of life, you can not ignore the plethora of striking behaviors and morphologies that have been the handiwork of sexual selection. The peacock’s tail is one emblematic result, but a compendium would also include: the songs of birds, frogs, and crickets, the brilliant colors of fishes and corals, the complex odors of moths and mustelids, and the differences ...
متن کاملMate choice and genetic monogamy in a biparental, colonial fish
In socially monogamous species, in which both sexes provide essential parental care, males as well as females are expected to be choosy. Whereas hundreds of studies have examined monogamy in biparental birds, only several such studies exist in fish. We examined mate choice in the biparental, colonial cichlid fish Neolamprologus caudopunctatus in Lake Tanganyika, Zambia. We genotyped more than 3...
