Alternative Mutational Architectures Producing Identical M-Matrices can Lead to Different Patterns of Evolutionary Divergence.

Abstract excerpt

Explaining macroevolutionary divergence in light of population genetics requires understanding the extent to which the patterns of mutational input contribute to long-term trends. In the context of quantitative traits, mutational input is typically described by the mutational variance-covariance matrix, the M-matrix, which summarizes phenotypic variances and covariances introduced by new mutations per generation....
