Explanation:

Mendel is known as the father of genetics. The concept of dominance and recessive trait was explained by Mendel while working on the pea plant Pisum sativum.

The individual has two alleles for a particular trait. The dominant trait is expressed in the individual in homozygous dominant and in heterozygous condition as well. The recessive trait is only observed in case of homozygous recessive condition. The dominant trait hides the expression of recessive trait in heterozygous condition.

Thus, the correct answer is option (3).
