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

SOS:

The answer is 9:3:3:1!

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

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

Hope this helps!
