Figure 4. (A) Distribution of pairwise relatedness coefficients in a Mediterranean population of gilthead sea bream Sparus aurata from Southern France estimated using 34,000 SNPs (Gagnaire P-A, unpublished data). All samples are juveniles from the same cohort, red arrows indicate 2 half-sib pairs with relatedness coefficients close to 0.25, and orange arrows 6 pairs of individuals which are likely first cousins (relatedness coefficients close to 0.125). (B) The predicted standard error and power of SNP heritability estimate for a true heritability of h<sup>2 </sup>=<sup> </sup>0.3, given the observed variance of pairwise relatedness coefficients in the sea bream population sample ( ). Power is the probability of detecting h<sup>2 </sup>><sup> </sup>0 given a type I error rate of Standard error and power were estimated using GCTA-GREML Power Calculator (Visscher et al. 2014).
