If mendel's dihybrid cross would have supported the theory of dependent assortment (rather than the theory of independent assortment), the phenotypic ratio of the cross in the f2 generation would have been
a. 9: 3: 3: 1
b. 2: 1: 1
c. 3: 1
d. 1: 1

C) 3:1

Explanation: Dependent Assortment says that alleles of two characteristics will be present on the same homologous pair of the chromosome . Simply that alleles are physically linked to each other.

Example -

T- Tall

Y- Yellow

t- short

y- white

T which is (tall) is physically linked with Y (yellow),

whereas t (short) is physically linked with y (white).
