Larval exposure to microorganism-enriched seawater did not result in genetic selection. a PCA of genome-wide SNP allele frequencies in F0 female (orange) and male (yellow) gametes (star) leading to generation F1 and from F1 (square) and F2 (triangles) generations of the control (blue) and ME-exposed (pink) lineages. b Histogram of p-val obtained when comparing allele frequencies between the ME-exposed and control oysters using the FLK test, for generations F1 (left) and F2 (right). P-val was plotted using R. Each sample included 30 pooled juvenile individuals sampled at day 120
