Question

6. Make a Punnett square for the cross between two

heterozygous birds.
7. What is the probability that the offspring of this cross will
have red coloring?
8. What precentage of possible offspring will have RR, Rr, or
rr genotypes?

Answer 1

6. picture is shown below

7. 75%

8. RR - 25% Rr - 50% rr - 25%

Step-by-step explanation:

6. I drew a the punnet square to show how to find the answer

7. Because R is the dominant red gene since all probabilities that have R in them is 3 3/4 is 75%

8. 1 RR = 1/4 = 25 %

2 Rr = 2/4 = 50 %

1 rr = 1/4 = 25%
