Fig. 1From: Sex determination in the GIFT strain of tilapia is controlled by a locus in linkage group 23Genome-wide association plots, from combined families of Stirling (a) and GIFT (b). Each dot represents a SNP and the Y-axis represents the magnitude of association (−log10P value of F-test) of the SNP with phenotypic sex, while the X-axis represents the position in the linkage groups of the assembled Nile tilapia genome. The alternating blue and green colours are used to distinguish between chromosomes. The red solid line represents a q-value of 0.05 and the blue solid line represents a q-value of 0.01 (adjusted to take multiple tests into account). a SNPs significantly associated with the phenotypic sex were identified in LG1 for Stirling families b SNPs in LG23 showed highest significant association with the phenotypic sex in GIFT familiesBack to article page
