Which one of the following can be explained on 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 \(F_2\) 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.

Choose the correct answer from the options given below:

1. A, B, C, D and E

2. A, B and C only

3. A, C, D and E only

4. B, C and D only

Best answer

Answer: 3. A, C, D and E only

Key idea: the Law of Dominance covers factors in pairs, dominant and recessive factors, and expression of only one parental trait in \(F_1\).

A, C, D and E are parts of this law. Statement B (both characters appearing as such in \(F_2\), with no expression of alleles) is incorrect for dominance; the reappearance of the recessive trait in \(F_2\) is explained by the Law of Segregation.
