Inbreeding avoidance among spawning adults
Among the four potential relatedness estimators considered, the Queller and Goodnight (1989) coefficient displayed the highest correlation between observed and expected values of relatedness (Pearson’s correlation coefficient = 0.924). Observed relatedness among parents that were and were not assigned progeny was -0.00087 and 0.00015, respectively (Figure 3 ). Expected levels of relatedness among individuals that were and were not assigned progeny were -0.00059 (SD: 0.00260) and -0.00068 (0.00157), respectively (Figure 3 ). Neither value of observed relatedness within a group was significantly different than expected values (assigned progeny: p < 0.49 and not assigned progeny: p < 0.46).
