Question

A person who is said to be heterozygous has

• A. Two dominant alleles
• B. Two recessive alleles
• C. One dominant allele and one recessive allele
• D. One dominant trait and one recessive trait

Answer 1

The correct option is C

One dominant allele and one recessive allele

Each gene has two alternative forms called alleles of which, one is expressive and is called the dominant allele. The other one is the recessive allele which is not expressive. Heterozygous individuals have one dominant and one recessive allele whereas homozygous individuals would have two alleles of the same type, i.e., either both dominant or both recessive.
