Answer 2

If two traits cross and the outcome is the presence of both traits together, it is codominance.

Answer: Option A

Explanation:

When a cross is made between alleles of two traits, if both the traits gets expressed in the F1 generation offspring it is called as codominance. In this type of crossing both the traits gets equally expressed in the offspring leading to a different phontype which is different from the parent.

For example, when a cross is made between white and red flower, the formation of pink color flower in f1 generation explains that it is due to codominance.
