Which of the following is not a Mendelian law of inheritance?

Correct answer: (d) Law of purity of gametes

Explanation

Mendel's three laws of inheritance are:

• the law of dominance;
• the law of segregation;
• the law of independent assortment.

The law of purity of gametes is not a separate law: it is another name for the law of segregation. Each gamete is "pure" because it carries only one allele of each gene. So it is the option that is not a distinct Mendelian law.
