Give one reason Mendel chose pea plants for his experiment.

Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons:

presence of observable traits with contrasting forms
produces many offspring in one cross
short life cycle
ease in manipulating pollination (cross-pollination)

Pea plants had the following characteristics:-

plants were sexually reproducing with bisexual flowers
self-pollination and self-fertilization is possible
the life cycle was completed in one season
hybrids were perfectly fertile
many varieties with well-defined characters were available i.e. presence of seven pairs of contrasting or allelomorphic characters
