Horse domestication and conservation genetics of Przewalski's horse inferred from sex chromosomal and autosomal sequences.
Despite their ability to interbreed and produce fertile offspring, there is continued disagreement about the genetic relationship of the domestic horse (Equus caballus) to its endangered wild relative, Przewalski's horse (Equus przewalskii). Analyses have differed as to whether or not Przewalski's horse is placed phylogenetically as a separate sister group to domestic horses. Because Przewalski...
متن کاملGenomic signatures of sex-biased demography: progress and prospects.
Sex-biased demographic events have played a crucial role in shaping human history. Many of these processes affect genetic variation and can therefore leave detectable signatures in the genome because autosomal, X-linked, Y-linked, and mitochondrial DNA inheritance differ between sexes. Here, we discuss how sex-biased processes shape patterns of genetic diversity across the genome, review recent...
متن کاملBeyond 2/3 and 1/3: The Complex Signatures of Sex-Biased Admixture on the X Chromosome
Sex-biased demography, in which parameters governing migration and population size differ between females and males, has been studied through comparisons of X chromosomes, which are inherited sex-specifically, and autosomes, which are not. A common form of sex bias in humans is sex-biased admixture, in which at least one of the source populations differs in its proportions of females and males ...
متن کاملContribution of X Chromosomal and Autosomal Genes to Species Differences in Male Courtship Songs of the Drosophila Virilis Group Species
In sympatric Drosophila species, songs produced by male wing vibration during courtship are an effective mechanism preventing interspecific matings and maintaining sexual isolation between different species. These songs can vary greatly even between closely related species. The aim of this study was to localise X chromosomal and autosomal genes affecting species differences in male courtship so...
متن کاملGenomic imprinting, sex-biased dispersal, and social behavior.
Some genes carry a record of the sex of the gene's carrier in the previous generation that influences the gene's expression in this generation. This additional information can result in intragenomic conflicts between an individual's maternally and paternally derived alleles over behaviors that affect relatives with whom the individual has different degrees of maternal and paternal relatedness. ...
