Question

Which one of the following can be explained as the basis of Mendel's Law of dominance?
A: Out of one pair of factors, one is dominant and the other is recessive.
B: Alleles do not show any expression and both the characters appear as such in F2 generation.
C: Factors occur in pairs in normal diploid plants.
D: The discrete unit controlling a particular character is called factor.
E: The expression of only one of the parental characters is found in a monohybrid cross.

Accepted Answer

, the Law of Dominance is defined by three statements: (i) Characters are controlled by discrete units called factors (Statement D); (ii) Factors occur in pairs (Statement C); (iii) In a dissimilar pair of factors one member of the pair dominates (dominant) the other (recessive) (Statement A). The law is used to explain the expression of only one of the parental characters in a monohybrid cross in the F1 generation (Statement E) . Statement B refers to the fact that alleles do not show any blending, which is the basis for the Law of Segregation .
