Pea plants were particularly well suited for use in Mendel's breeding experiments for all of the following reasons except that
A) peas show easily observed variations in a number of characters, such as pea shape and flower color.
B) it is possible to completely control matings between different pea plants.
C) it is possible to obtain large numbers of progeny from any given cross.
D) peas have an unusually long generation time.
E) many of the observable characters that vary in pea plants are controlled by single genes.

Mendel while working on the pea plants, discovered the three fundamental laws of inheritance. Mendel chose the pea plant due to the plant's bisexuality, distinct traits, and are self-pollinating.

The correct option is:

Option E. many of the observable characters that vary in pea plants are controlled by single genes.

The pea plants were selected by Mendel due to following reasons:

Pea plants were bisexual and were easy to breed.

The matings between different types of pea plants were easy to control.

The generation time of pea plants is usually long.

A large number of offspring can be obtained from different types of cross.

Pea plants are self-pollinating and express several traits like flower color and plant height.

Therefore, the option that is not suited best for pea plant breeding experiments is Option E.
