Bivariate Model: traits A and B measured in twins

Bivariate Model: traits A and B measured in twins. cb. ca. Questions. Do the genes that influence trait B also influence trait A? Are there genes that are unique to trait A? Is the phenotypic correlation caused by genetic correlation?

Lecture 3: Resemblance Between Relatives

Lecture 3: Resemblance Between Relatives. Heritability. Central concept in quantitative genetics Proportion of variation due to additive genetic values (Breeding values) h 2 = V A /V P Phenotypes (and hence V P ) can be directly measured Breeding values (and hence V A ) must be estimated
