In Jabberwocks, flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b). Jabberwock geneticists suspect that the two genes are linked on one of the autosomes
They mate a true-breeding flame-eyed, burbling female with a true-breeding blue
-eyed, whistling male. They then remove a sample of gametes from one of the resulting
offspring. If the genes are linked, which of the following is/are a recombinant gamete
genotype? Select all correct choices:
A. FB
B. Fb
C. fb
D. fB
E. none of these is a recombinant gamete
genotype
