In zebrafish, three genes have been mapped on the third chromosome, in the order fiz---6 m. u.---myob14 m. u.sufi The wild-type allele of each gene is dominant. A strain that is fiz myob sufi / + + + is testcrossed, and there are 1000 offspring fish.

(1) How many wild-type offspring would you expect to see in these 1000 offspring?
(2) How many fiz + + offspring would you expect to see in these 1000 offspring?
