Back to the cute little pigs. What are the possible parents of the following groups of guinea pigs. Give all possibilities. You do not need to show Punnett Squares, just the possible parents. There may be more than I answer for each. Case 1: 50 % of the offspring are black Case 2: 75 % of the offspring are black Case 3: 50 % of the offspring are hybrid black Case 4: 100 % of the offspring are black Case 5: 100 % of the offspring are white Case 6: 50 % of the offspring are white Case 7: 25 % of the offspring are white​

Case 1 ⇒ Bb   x   bb ⇒ F1 = 50% Bb, black + 50% bb, white

Case 2 ⇒ Bb   x   Bb ⇒ F1 = 75% Black + 25% white

Case 3 ⇒ Bb   x   Bb ⇒ F1 = 25% BB + 50% Bb + 25% bb

            ⇒ Bb   x   bb ⇒ F1 = 50% Bb + 50% bb

Case 4 ⇒  BB   x   BB ⇒ F1 = 100% BB Black

            ⇒ Bb   x   BB ⇒ F1 = 50% BB + 50% Bb = 100% Black

            ⇒ bb   x   BB ⇒ F1 = 100% Bb black

Case 5 ⇒ bb   x   bb ⇒  F1 = 100% bb white

Case 6 ⇒ Bb   x   bb ⇒ F1 = 50% Bb black + 50% bb white

Case 7 ⇒ Bb  x  Bb ⇒ F1 = 75% black + 25% white

Explanation:

Due to technical problems, you will find the complete explanation in the attached files

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
