FIGURE 2.

DHB was clustered differently in terms of body weight and genetic composition. (a) Body weight of the 20 Chinese local pig breeds. Body weight is the sow weight of the breed collected from the book of Wang et al. (2011). (b) PCA projection of pig breeds using whole‐genome SNPs. PC1 and PC2 explained 5.55% and 3.65% genetic variance, respectively. 95% confidence ellipses were drawn for the two groups of large‐sized and small‐sized breeds.
