Question

When both alleles of a heterozygous gene are fully expressed, neither

is dominant nor recessive, is called------.

A) Co-Dominance B) Incomplete Dominance

C) Over Dominance D) Complete Dominance
​

Answer 1

Explanation:

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
