Population genetic analysis of Dabasha crossbred line. A Principal component analysis of all sample individuals. The fraction of the variance explained is 22.08% and 9.01% for PC1 and PC2, respectively. B Neighbor-Joining phylogenetic tree of all sample individuals. 0.04 in the bottom of the tree represented same branch length’s nucleotide mutation was 4% (Each of 100nts had 4 mutations on average) and the number at nodes indicated mostly 100 bootstrap supports. C Linkage disequilibrium decay of five populations measured by r2. D When K = 3, population structure of all individuals. Red represents the genetic background from B, while green represents S and Blue represents Y
