Discovering All Transcriptome Single-Nucleotide Polymorphisms and Scanning for Selection Signatures in Ducks (Anas platyrhynchos).

ABSTRACT: The duck is one of the most economically important waterfowl as a source of meat, eggs, and feathers. Characterizing the genetic variation in duck species is an important step toward linking genes or genomic regions with phenotypes. Human-driven selection during duck domestication and subsequent breed formation has likely left detectable signatures in duck genome. In this study, we employed a panel of >1.4 million single-nucleotide polymorphisms (SNPs) identified from the RNA sequencing (RNA-seq) data of 15 duck individuals. The density of the resulting SNPs is significantly positively correlated with the density of genes across the duck genome, which demonstrates that the usage of the RNA-seq data allowed us to enrich variant functional categories, such as coding exons, untranslated regio
