Q. 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 pair 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:
A) B, C and D only
B) A, B, C, D and E
C) A, B and C only
D) A, C, D and E only
Explanation
[Solution by Claude - not from source] The law of dominance covers factors in pairs, dominant and recessive factors, and expression of one parental character in the monohybrid $F_1$. B (no expression of alleles) is incorrect. Answer (4).
