(a) Complete dominance

(b) Incomplete dominance

(c) Codominance

(d) Multiple allelism

This question was posed to me in a national level competition.

This interesting question is from Inheritance Principles in portion Principles of Inheritance and Variation of Biology – Class 12

Right answer is (d) Multiple allelism

Explanation: In multiple allelism, more than one allele can be present at a locus. This results in the production of many different phenotypes.
