In which situation are the phenotypes of F2 offspring expected to follow the ratio of 9:3:3:1 a. A monohybrid cross for 2 unlinked traits b. A monohybrid cross for 2 closely linked traits c. A dihybrid cross for 2 unlinked traits d. A dihybrid cross for 2 closely linked traits

C, dihybrid cross of 2 unlinked traits.

Explanation: The phenotypic ratio of 9:3:3:1 is achieved in a dihybrid cross involving two unlinked traits. Example, a dihybrid cross involving two different colours and two different shapes of fruit. Eg, green and yellow, round and wrinkled.

i believe the answer would be b. hope it : )
