Question

If an individual is heterozygous for a particular trait

A. each parent contributed a different allele for that trait.
B. each parent contributed the same allele for that trait.
C. one parent contributed two different alleles for that trait.
D. one parent contributed two copies of the same allele for that trait.
E. a mutation must have occurred.

Answer 1

If an individual is heterozygous for a particular trait, it means that (Option A) each parent contributed a different allele for that trait. This results in a combination of different alleles for that trait, and the individual will have a phenotype similar to that of an individual with two dominant alleles for the trait.

Step-by-step explanation:

In the language of genetics, if an individual is heterozygous for a particular trait, it means that each parent contributed a different allele for that trait.

This means that the individual received one allele from the mother and one allele from the father, resulting in a combination of different alleles for that trait. In this case, the individual will have a phenotype similar to that of an individual with two dominant alleles for the trait.
