Explanation:
Detailed explanation-1: -The three laws of inheritance proposed by Mendel include: Law of Dominance. Law of Segregation. Law of Independent Assortment.
Detailed explanation-2: -The Mendel’s four postulates and laws of inheritance are: (1) Principles of Paired Factors (2) Principle of Dominance(3) Law of Segregation or Law of Purity of Gametes (Mendel’s First Law of Inheritance) and (4) Law of Independent Assortment (Mendel’s Second Law of Inheritance).
Detailed explanation-3: -Multiple alleles, incomplete dominance, and codominance (article) Pleiotropy and lethal alleles (article) Sex-linked traits (video)
Detailed explanation-4: -So, the correct option is ‘Law of incomplete dominance’.
