European hair and eye color: A case of frequency-dependent sexual selection?
Human hair and eye color is unusually diverse in northern and eastern Europe. The many alleles involved (at least seven for hair color) and their independent origin over a short span of evolutionary time indicate some kind of selection. Sexual selection is particularly indicated because it is known to favor color traits and color polymorphisms. In addition, hair and eye color is most diverse in...
متن کاملThe Genetic Overlap Between Hair and Eye Color.
We identified the genetic variants for eye color by Genome-Wide Association Study (GWAS) in a Dutch Caucasian family-based population sample and examined the genetic correlation between hair and eye color using data from unrelated participants from the Netherlands Twin Register. With the Genome-wide Complex Trait Analysis software package, we found strong genetic correlations between various co...
متن کاملHealth status by gender, hair color, and eye color: Red-haired women are the most divergent
Red hair is associated in women with pain sensitivity. This medical condition, and perhaps others, seems facilitated by the combination of being red-haired and female. We tested this hypothesis by questioning a large sample of Czech and Slovak respondents about the natural redness and darkness of their hair, their natural eye color, their physical and mental health (24 categories), and other pe...
متن کاملGenome-Wide Association Studies of Quantitatively Measured Skin, Hair, and Eye Pigmentation in Four European Populations
Pigmentation of the skin, hair, and eyes varies both within and between human populations. Identifying the genes and alleles underlying this variation has been the goal of many candidate gene and several genome-wide association studies (GWAS). Most GWAS for pigmentary traits to date have been based on subjective phenotypes using categorical scales. But skin, hair, and eye pigmentation vary cont...
متن کاملOn Hair Color in France
Sex-linked coloration is a familiar phenomenon in the animal kingdom. Most people are familiar with the bright coloration of the male in many species of birds [2]. Instances of sex-linking of hair color in mammals are rare, but not unknown. For example, the tricolor pattern in the domestic house cat felix domesticus is found almost exclusively in the female [4]. We report here our discovery of ...
