Solution

The correct option is C
Independent assortment

The correct option is C:
Explanation of the correct option :
Law of independent assortment states that the unit factor of each character is assorted or distributed into the gametes independently of the unit factor of any other character and gets randomly rearranged in the offspring.
E.g. blood group and color of hair does not depend on each other for their inheritance.
Explanation of the incorrect options:
Option A:
Law of dominance states that out of two factors only one is able to express itself in the F₁ generation and it prevent expression of the other.
Option B:
Multiple alleles is a type of non-Mendelian inheritance pattern that involves more than two alleles code for a certain characteristic in a species.
Option D:
Incomplete dominance results from a cross in which each parental contribution is genetically unique and gives rise to progeny whose phenotype is intermediate.
Final answer: Some individuals with blood group A may inherit the genes for blond hair, while other individual with blood group A may inherit the gene for brown hair. This can be best explained by the principle of independent assortment.
