    Which one 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

    Correct Answer: C

    Solution :

    [c] Option [c] cannot be explained on the basis of Mendel's law of dominance. When \[{{F}_{1}}\] hybrids exhibit a mixture or blending of characters of two parents, the case is considered as that of incomplete blending inheritance. It simply means that the two genes of an allomorphic pair are not related as dominant or recessive, but each of them can express itself partially.
