Figure 1. Genetic differential among population crosses. Single Nucleotide Polymorphism (SNP) cluster analysis for 68 individually genotyped Acropora spathulata larvae produced from five reproductive crosses (red: WW1, WW2, WW3), warm-cool (yellow: WC), cool-warm (blue: CW). (A) Principal Coordinates Analysis and(B) Discriminant Analysis of Principal Components (DAPC) of genetic structure across the SNP dataset. Point colors correspond to five genetic crosses. (C) Admixture inference using DAPC atk = 5. Each vertical bar represents an individually genotyped larva, with colors indicative of the membership probability for that population into each of the assigned genetic clusters.
