Question

Differentiate between mass selection and pure line selection

Answer 1

Answer:

The main difference between mass selection and pure line selection is that a mass selection contains a mixture of pure lines, whereas a pure line selection contains a set of uniform characteristics. Furthermore, in a mass selection, both self- and cross-pollinated species occur while only self-pollinated species occur in a pure line selection. Moreover, genetic variation is present in a mass selection, while genetic variation does not occur in a pure line selection.

Mass selection and pure line selection are two types of selective breeding methods used to improve crops. Generally, they belong to artificial selection methods along with the clonal selection, which is another selection method
