Estimating the strength of sexual selection from Y-chromosome and mitochondrial DNA diversity.
We show that a sex difference in the opportunity for selection results in sex differences in the strength of random genetic drift and thus creates different patterns of genetic diversity for maternally and paternally inherited haploid genes. We derive the effective population size Ne for a male-limited or female-limited haploid gene in terms of I, the "opportunity for selection" or the variance...
متن کاملMitochondrial DNA and Y chromosome diversity and the peopling of the Americas: evolutionary and demographic evidence.
A number of important insights into the peopling of the New World have been gained through molecular genetic studies of Siberian and Native American populations. While there is no complete agreement on the interpretation of the mitochondrial DNA (mtDNA) and Y chromosome (NRY) data from these groups, several generalizations can be made. To begin with, the primary migration of ancestral Asians ex...
متن کاملDHPLC Applications: Finding DNA Variation on the Y Chromosome
Denaturing High-Performance Liquid Chromatography (DHPLC) is a recently developed technique forthe detection of single nucleotide polymorphisms (SNPs) and mutations. It involves the comparisonbetween two or more DNAs as a mixture of denatured and reannealed PCR products. The methodologyis based on the principle of reversed phase liquid chromatography and uses a unique DNA sepa...
متن کاملMitochondrial DNA and Y-chromosome variation in the caucasus.
We have analyzed mtDNA HVI sequences and Y chromosome haplogroups based on 11 binary markers in 371 individuals, from 11 populations in the Caucasus and the neighbouring countries of Turkey and Iran. Y chromosome haplogroup diversity in the Caucasus was almost as high as in Central Asia and the Near East, and significantly higher than in Europe. More than 27% of the variance in Y-haplogroups ca...
متن کاملUnexpected island effects at an extreme: reduced Y chromosome and mitochondrial DNA diversity in Nias.
The amount of genetic diversity in a population is determined by demographic and selection events in its history. Human populations which exhibit greatly reduced overall genetic diversity, presumably resulting from severe bottlenecks or founder events, are particularly interesting, not least because of their potential to serve as valuable resources for health studies. Here, we present an unexpe...
