Population genetics of the studied duck populations. a Geographic location of the studied ducks (sampling map is drawn using the ggmap package in R). The symbols used for each population correspond to those in (d). Additional details are in Additional file 1: Table S1. b Neighbor-joining phylogenetic tree constructed using whole-genome SNP data. SEA/SA is an abbreviation for Southeast/South Asian, where blue and grey are Southeast Asian and South Asian populations, respectively. Cyan-blue represents LC × BY duck lineages from China. Cairna moschata is the outgroup. c Principal component (PC) plots using the first two principal components. The fraction of the variance explained is 8.66% for PC1 and 4.15% for PC2. d Genetic structure of the populations. The length of each colored segment represents the proportion of the individual’s genome from K = 3 to 4 ancestral populations. The geographic locations are at the bottom of the figure
