Answer:
Correct Answer: B
Solution:
Mendel chose garden pea as plant material for his experiments, since it had the following advantages : (i) Well defined characters.
(ii) Bisexual flowers.
(iii) Predominantly self-fertilization.
(iv) Easy hybridization.
Besides these features, garden pea, being self-fertilized, had pure lines due to natural self-fertilization for a number of years.
Therefore, any variety used was pure for the characters it carried.
Mendel?s success was mainly based on the fact that he considered a single character at one time.
