Figure 2.Selective breeding across
populations creates signficanlty greater genetic variation across the
coral genome. Distribution of allele frequencies for purebred and
hybrid offspring groups consisting of warm-warm crosses (red: WW),
warm-cool (yellow: WC yellow), cool-warm (blue: CW) for individually
genotyped larvae reared at 27.5°C. Black lines correspond to modelled
theoretically expected Hardy-Weinberg distributions of allele
frequencies simulated for the three population sizes (n = WW: 34, WC:
15, CW: 19). Theoretical versus expected allele frequencies differed
signficantly within population crosses (Kolmogorov-Smirnov Two-Sample
test, WW: p = 1.0e-45, WC: 2.2e-46 and CW: 1.0e-45) and between
purebred and hybrid crosses (WW versus WC: 2.1e-26, WW versus CW:
1.3e-21) but not between hybrids (WC versus CW: 0.34).
