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 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.
- 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
Mendel's Law of Dominance states: characters are controlled by discrete units called factors (D); factors occur in pairs (C); in a dissimilar pair, one member dominates the other (A); and only the dominant character is expressed in a monohybrid F cross (E). Statement B is incorrect as it contradicts dominance. Hence A, C, D and E.
