Four previously unreported SNPs in the duck MITF gene. (a) g.312C>T site; (b) g.32813G>A site; (c) g.39807T>G site; (d) g.40862G>A site. Five individuals from each breed (N = 20) were randomly selected for Sanger sequencing. Asterisk showed mutation sites. The SNPs were mainly observed in PTB and LS ducks according to the reference sequence of Peking duck.
