FIGURE 2.

(a) Genetic differentiation among the self‐recruiting oysters from Pendrell Sound (PEN), France (FRA), China (CHN), and Japan (JPN) compared to oysters sampled from farms thought to be growing strains descended from the same lineage (ROS, DPB, GUR). China is compared to the farms growing oysters thought to originate from China (QDC, RSC). (b) Discriminant analysis of principal components (DAPC) using all populations in the analysis indicates the similarity among BC populations, Japan, and France (peaks between 0–4 along discriminant function), among the Chinese populations (peaks between −4 to −10), and the distinct GUR (peak at 5) and DPB populations (peak at 9)
