Question

Being right-handed (R) is dominant over being left-handed(r), and having freckles (F) is dominant over not having freckles (f). Two parents are both heterozygous for both traits. What are the chances of having offspring(s) that are right-handed with freckles?

1/16
4/16
10/16
9/16

Answer 1

9/16

Step-by-step explanation:

3/4 chances for both of them

3/4×3/4=9/16
