Y chromosome conserved anchored tagged sequences (YCATS) for the analysis of mammalian male‐specific DNA

Y chromosome haplotyping based on microsatellites or single nucleotide polymorphisms has recently proven to be a powerful approach for evolutionary studies of human populations, and also holds great promise for the studies of wild species. However, the use of the approach is hampered in most natural populations by the lack of Y chromosome markers and sequence information. Here, we report the large-scale development of Y chromosome conserved anchor tagged sequence (YCATS) markers in mammals by a polymerase chain reaction screening approach. Exonic primers flanking 48 different introns of Y-linked genes were developed based on human and mouse sequences, and screened on a set of 20 different mammals. On average…
