Evolutionary and Ecological Processes Determining the Properties of the G Matrix.

The American naturalist - 1 Nov 2024

Engen Steinar, Sæther Bernt-Erik

Abstract excerpt

AbstractThe G matrix is the matrix of additive genetic variances and covariances for a vector of phenotypes. Here we apply the classical theory for the balance among selection, genetic drift, and mutations to find the contributions to G from each locus for populations at stasis. The fitness is approximated by a linear function of phenotypes, with coefficients affected by environmental fluctuations. We show that...
