Answer 1

Dominant traits:

1. Dominant traits are those which are expressed in the offspring and mask the effect of another trait.
2. When one or two copies of the dominant allele are inherited in the second filial generation, it is said that the dominant trait has been expressed.

Recessive traits:

1. These are those traits that remain hidden and do not get expressed in the offspring.
2. The expression of these traits is seen but in very few offspring.

The pair of contrasting traits are:

1. Yellow seed- Dominant
   Green seed - Recessive
2. Round seed - Dominant
   Wrinkled seed - Recessive
