Answer 2

The correct answer will be option d.

• A single gene controls a single character.

The gene has different alleles.

For example, growth is controlled by a gene that has 2 alleles.

One allele is the recessive one and the other allele is dominant.

• There can also be multiple allelism, wherein a gene has multiple alleles for a specific character.

        For example, skin color.
