Experiments testing the "good genes" model of sexual selection are notoriously difficult
One problem is to separate environmental factors associated with a particular father (e.g., brood care by father) from the effect of a father's genetics. Which of the following experimental designs solves this problem?
a. randomize offspring environment by transplanting offspring to nests of different fathers
b. obtain very large sample sizes to factor out fathers' environmental influ-ence
c. use genetically identical fathers
d. This problem cannot be solved. We have to work only with species in which the father contributes nothing but its genetics.
e. A, B, and C.
