The mate choice brain: comparing gene profiles between female choice and male coercive poeciliids.
Genes that mediate mate preferences potentially play a key role in promoting and maintaining biological diversity. In this study, we compare mate preference behavior in two related poeciliid fishes with contrasting behavioral phenotypes and relate these behavioral differences to gene profiles in the brain. Results reveal that one poeciliid fish, the Northern swordtail, exhibits robust mate pref...
متن کاملFemale ornamentation and male mate choice in dark-eyed juncos
Traits that enhance attractiveness in one sex may or may not influence attractiveness in the other. In the dark-eyed junco, Junco hyemalis, outer tail feathers of males and females are all or partly white and form a sharp contrast with the bird’s mostly grey plumage. The amount of white in these feathers (‘tail white’) is greater in males than in females and, as we report here, is greater in bi...
متن کاملThe complexities of female mate choice and male polymorphisms: Elucidating the role of genetics, age, and mate-choice copying
Genetic, life history, and environmental factors dictate patterns of variation in sexual traits within and across populations, and thus the action and outcome of sexual selection. This study explores patterns of inheritance, diet, age, and mate-choice copying on the expression of male sexual signals and associated female mate choice in a phenotypically diverse group of Schizocosa wolf spiders. ...
متن کاملFemale mate choice in mammals.
Studies of mate choice in vertebrates have focused principally on birds, in which male ornaments are often highly developed, and have shown that females commonly select mates on the basis of particular phenotypic characteristics that may reflect their genetic quality. Studies of female mate choice in mammals are less highly developed and they have commonly focused on female mating preferences t...
متن کاملHow is female mate choice affected by male competition?
The plethora of studies devoted to the topics of male competition and female mate choice belie the fact that their interaction remains poorly understood. Indeed, on the question of whether competition should help or hinder the choice process, opinions scattered throughout the sexual selection literature seem unnecessarily polarised. We argue, in the light of recent theoretical and empirical adv...
