The genetic variance but not the genetic covariance of life-history traits changes towards the north in a time-constrained insect.

abstract：:Peacocks are a classic example of sexual selection, where females preferentially mate with males who have longer, more elaborate trains. One of the central hypotheses of sexual selection theory is that large or elaborate male 'ornaments' may signal high genetic quality (good genes). Good genes are thought to be those ...
