Q. Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: In an experiment, Mendel observed that the F1 progeny plants are all tall and none are dwarf. Reason R: Stem height is a contrasting trait, with tall being dominant and dwarf being recessive. In the light of the above statements, choose the most appropriate answer from the options given below:
A) A is not correct but R is correct
B) Both A and R are correct and R is the correct explanation of A
C) Both A and R are correct but R is not the correct explanation of A
D) A is correct but R is not correct
Explanation
[Solution from source] All F1 plants were tall because tall is dominant over dwarf, so the heterozygous F1 shows only the tall trait; R explains A. Answer (2).
