Maternal Genetic Covariance and Maternal Genetic Correlation Surfaces for Birthweight Expressed across Environments
(A) Maternal genetic covariance; (B) maternal genetic correlation. The maternal genetic correlation rM is close to +1 over most of the surface, suggesting that the same maternal loci are involved and have qualitatively similar effects on offspring birthweight across all environments.
