Document Summary
Females maybe choosing traits which are indicators of the genetic quality of the male. The genetic quality of the male is reflected in the trait which is called conditioned dependent. Much correlational support exists: if you go out and measure the expression of trait and health, it is correlated. Considerable experimental evidence exists raise males in different nutritional conditions. And if they are raised in good nutritional conditions you expect them to have these good dimorphism traits, if the nutr. Conditions are not good, then you cant seen developed traits. Variance in condition is usually generated with an environmental manipulation eg nutrition. The evolutionary interests of the sexes differ: 2. Therefore selection acting on the two sexes in an interaction (or on a single shared trait) will often be antagonistic: how wide spread is sexual conflict i, consider virtually all interactions between the sexes.
