For example, traits like flower color, seed shape, and plant height were easy to distinguish between individuals.

Contrasting characters refer to pairs of opposing traits for a single characteristic. For instance, for the seed shape trait, peas can either be round or wrinkled—these are the two contrasting characters. Mendel worked with seven such pairs of contrasting traits, such as:
