The evolution of dimorphic traits: predicting the genetic correlation between environments.

Genetics - 1 Jan 1994

Roff D A

Abstract excerpt

Many traits vary in a dichotomous manner, although the underlying genetic determination is polygenic. The genetic basis of such dimorphic traits can be analyzed using the threshold model, in which it is assumed that there is a continuously distributed underlying character and the phenotype is determined by whether the character is above or below a threshold. Threshold traits frequently vary with environmental...
