Identification of selection signatures in livestock species
The identification of regions that have undergone selection is one of the principal goals of theoretical and applied evolutionary genetics. Such studies can also provide information about the evolutionary processes involved in shaping genomes, as well as physical and functional information about genes/genomic regions. Domestication followed by breed formation and selection schemes has allowed t...

Intramuscular fat (IMF) content is an important trait affecting the quality of pork. Two Duroc populations selected for IMF were used to identify signatures of selection associated with IMF. The effects of selection were analyzed between selected and control animals within each population using principal component analysis and FST using 60k SNPs. Moreover, extended haplotype homozygosity-based ...
متن کاملA genome-wide scan to detect signatures of recent selection in Australian Merino sheep
Domestication and selection are processes that conserve the pattern of genetic diversities between and within populations. Identification of genomic regions that are targets of selection for phenotypic traits is one of the main aims of research in animal genetics. An approach for identifying divergently selected regions of the genome is to compare FST values among loci to estimate the genetic v...
متن کاملComparing Patterns of Natural Selection across Species Using Selective Signatures
Comparing gene expression profiles over many different conditions has led to insights that were not obvious from single experiments. In the same way, comparing patterns of natural selection across a set of ecologically distinct species may extend what can be learned from individual genome-wide surveys. Toward this end, we show how variation in protein evolutionary rates, after correcting for ge...
