sDYD relative difference between heterozygous and non-carrier rams for 6 selected traits. MY milk yield, FY fat yield, PY protein yield, FC fat content, PC protein content, LSCS Lactation somatic cell score, sDYD standardized daughter yield deviation (DYD divided by genetic standard deviation). Significant effects are indicated by the corrected P-value for multiple tests with a threshold set at α = 1%: *P < 3.1 × 10−4; **P < 3.1 × 10−5 and ***P < 3.1 × 10−6. Error bars indicate standard errors. Significant favorable effects of heterozygous are in green and significant unfavorable effects are in red
