The distribution of genetic variation among multiple traits is a key determinant of how a population will respond to selection (Lande, 1979; Schluter, 1996; Arnold et al., 2001). For the prediction of ...
The efficiency and direction of adaptive evolution are not only affected by the fitness landscape, but also by the amount and structure of heritable variation (Lande 1979; Teplitsky et al. 2014).
The COV= option must be specified to compute an approximate covariance matrix for the parameter estimates under asymptotic theory for least-squares, maximum-likelihood, or Bayesian estimation, with or ...
