There are two genetically distinct types of Gouldian nches. One has a red face, and the other has a black face. Previous experiments have shown that female nches have a strong preference for mating with males with the same face color as themselves, and that when different face tvpes of nch mate with one another, their offspring are less likely:I to survive. Researchers paired females sequentiallv with maies of both types in random order. Each time, females produced a 'orood of voung with the assigned male. For each pairing, blood corticosterone concentration was measured as an index of the amount of stress the females experienced. The data from this experiment are given in the le \"Stressndlncompatihlel'It'iatescs'rf.
