If the two traits that Mendel looked at in his dihybrid cross of smooth yellow peas with wrinkled green peas had been controlled
nalin [4]

Answer:

c. Would have deviated from the 9:3:3:1 phenotypic ratio

Explanation:

<em>If two genes are linked together on the same chromosome, the phenotype of the F2 generation would have deviated from 9:3:3:1.</em>

Two genes whose loci are close on the same chromosome are said to be linked. Linked genes have higher frequency of recombination than genes that are not linked.

<u>Hence, while genes that are not linked assort independently to produce 9:3:3:1 phenotypic ratio at F2, linked genes do not assort independently and the higher frequency of recombination ensures that they standard phenotypic ratio is deviated from.</u>

The correct option is c.
