a, PC analysis plots of the first two components. The fractions of the explained variance are 18.62% for PC1 and 13.28% for PC2. b, Phylogenetic tree constructed using the nuclear genome. The nodes with solid black circles are 100% bootstrap supported. The divergence times of C. gibelio and C. auratus (T3) and of three C. gibelio strains (T4) are shown at corresponding nodes. c, Different epochs of C. gibelio and C. auratus evolution with times. Single lines indicate haploid gametes, and double lines indicate diploid gametes. Red squares with a single-line arrow and double-line arrow represent normal fertilization and genome doubling after fertilization, respectively.
