If such traits are negatively correlated with each other , there may be little additive genetic variance in fitness ... The evolution of a polygenic trait thus depends on the heritability and on the way in which selection acts on the ...

If two polygenic traits are each subject to stabilizing selection and they are governed by different sets of genes ... One possibility is that variation in a quantitative trait such as bristle number does not in itself affect fitness ...

It is not sufficient to draw a correlation merely by counting species with one or another trait , because ecologically similar species may be closely related and therefore share a trait solely because of common ancestry .
