Answer:

Parents: Yellow (Aarr) and Grey (AaRr)

Explanation:

Given:

allele A = yellow

allele R = black,

Heteroozygous = gray

Genotypes of the parents:

yellow (Aarr) - female

gray (AaRr) - gray

cross between these

Parents: Yellow (Aarr) and Grey (AaRr)

Gametes: (Ar, ar) and (AR, Ar, aR, ar)

F1 (Punnet square)

----|----- AR ------|------- Ar ------|------ aR -----|----- ar

Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)

ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)

Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black
