Which of the following statements correctly explains the fact that all seven of the pea plant traits studied by Mendel obeyed the principle of independent assortment?

A) All of the genes controlling the traits behaved as if they were on different chromosomes.

B) All of the genes controlling the traits were located on the same chromosome.

C) None of the traits obeyed the law of segregation.

D) The diploid number of chromosomes in the pea plants was seven.

Answer: Option A

Explanation:

Mendel used many the same pea plants for the description of many characters independently in those pea plants only.

The Principal of Independent Assortment states how different genes express themselves independently when reproductive cells develop.

This was first observed by Mendel by his experiments. Every character of the pea plants that he used appeared independently. None of the two characters got mixed with one another.

Hence, the correct answer is option A
