文摘
- •
We explore how epistasis affects heritable multivariate trait variation and evolvability.
- •
Epistatic genetic effects map differently genealogically than additive genetic effects.
- •
Which leads to less relative covariance in genotypic and breeding values between individuals.
- •
Which allows for greater heritable multivariate variation and evolvability.
