Question

The phenotypic ratio for the F2 generation in a dihybrid cross will theoretically be _____.

1:2:1
1:3
9:3:3:1
1:2:2:1

Answer 1

SOS:

The answer is 9:3:3:1!

The F2 generation exhibits four different phenotypes, as follows:↓↓↓↓↓↓↓↓

• yellow, round seeds (both dominant traits) - 9/16
• yellow, wrinkled seeds (one dominant and one recessive trait) - 3/16
• green, round seeds (one recessive and one dominant trait) - 3/16
• green, wrinkled seeds (both recessive traits) - 1/16

Hope this helps!

Answer 2

9:3:3:1 Im pretty sure...........
