Agouti, rusty black and brown are coat color variants in mice. From a randomly-breeding mouse colony you obtain the data shown below. What phenotypic distributions in the offspring are possible if you crossed the female parent in family 7 with the male parent in family 6? Explain your answer.

Explanation / Answer

Agouti is dominant over black (From phenotypes of parent family 2)

Rusty is dominant over agouti (From phenotypes of parent family 5)

Black is dominant over brown (Expressed only in homozygous recessive condition. From phenotypes of parent family 7)

When female parent in family 7 (Black- CbCa) with the male parent in family 6 (Rusty
