Definition: Heterozygous means having two different alleles of a particular gene, one inherited from each parent.

Examples:
- A pea plant with genotype Tt (one tall allele T and one short allele t) is heterozygous for height.
- A person with one normal hemoglobin allele and one sickle-cell allele (HbA/HbS) is heterozygous for the sickle-cell gene and typically carries the sickle-cell trait.

Sentence using it: The mouse is heterozygous at the coat-color gene, so it displays the dominant coloration while carrying a recessive allele.
