Ramiro · Answer 1

The exact explanation for co dominance is that in a heterozygote, both alleles are expressed.

Answer: Option B

Explanation:

Mendel drafted certain terminologies in the history of genetics such as dominance and recessive traits. But later after Mendel, certain scientists found out some exceptions for this concept such as codominance, incomplete dominance and linkage.

Among this codominance is a trait in which for a heterozygote individual has both the characters expressed for example when a red flower and a white flower are mixed, the resulting flower is pink in color.
