(a) The transmission of characters from parents to the offspring’s is called heredity. The units of heredity are genes.
(b) According to Mendel’s first law of inheritance:
The characteristics (or traits) of an organism are determined by internal ‘factors’ which occur in pairs. Only one of a pair of such factors can be present in a single gamete.
