Figure 4From: Casein SNP in Norwegian goats: additive and dominance effects on milk composition and qualitySNP's additive effect on milk taste and FFA concentration in milk expressed as test statistics for frequent alleles. Test statistics (estimated effects divided by their standard errors) are embedded in the y-axis; the horizontal lines indicate 5% experiment-wise level of significance and any SNP having a test statistic value for a trait above the top line or below the bottom line indicates that it has a significant effect on the trait.Back to article page
