Q. Which of the following cannot be explained on the basis of Mendel’s Law of Dominance?
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 the characters recover as such in $F_{2}$ generation
D) Factors occur in pairs
Explanation
When $F_{1}$ hybrids exhibited a mixture on blending of chararcters of two parents, the case is considered as that of incomplete blending inheritance. It simply means that the two genes of allelomorphic pair are not related as dominant or recessive, but each them express itself partially.
