Natural selection on body size in Tribolium: possible genetic constraints on adaptive evolution.

Heredity - 1 Jul 1992

Conner J, Via S

Abstract excerpt

To determine whether genetic constraints on adaptive evolution were operating in a laboratory population of a flour beetle, Tribolium castaneum, we first estimated the direct selection acting on each of several body size traits. Strong selection in males for an increase in pupal weight and a decrease in the ratio of adult to pupal weight occurred. In addition, a non-significant trend for a decrease in adult width...
