Which one of the following cannot be explained on the basis of Mendel's Law of dominance

Options

A. The discrete unit controlling a particular character is called a factor
B. Out of one pair of factors one is dominant, and the other is recessive
C. Alleles do not show any blending and both thee characters recover as such in `F_(2)` -generation
D. Factors occur in pairs

Answer

C

Explanation

When `F_(1)` hybrids exhibit a mixture on blending of characters of two parents, the case is considered as that of incomplete blending inheritance. It smply means that the two genes of allelomorphic pair are not related as dominant or recessive, but each of them expres itself partially.
