is it important to understand the genetic basis of coloration?
has it been previously assumed that carotenoid-based
coloration is only a function of the environment? Why is this assumption unjustified?
some of the sources of variance that were included in their analyses that
you may not have thought of before.
Explain why one of these is important.
was the purpose of the cross-fostering experiment? Did cross-fostering influence the
estimate of heritability? What is
the significance of this finding?
an example of an environmental effect that persisted through multiple life
stages. Are you surprised by this
result? Why or why not?
