That's a great question! The term for an organism having different genes for a trait is heterozygous.

Here's a breakdown:

* Heterozygous: Means having two different alleles (versions of a gene) for a particular trait.

* Allele: A specific version of a gene.

* Trait: A characteristic of an organism, such as eye color, height, or hair texture.

For example, if a person has one allele for brown eyes and one allele for blue eyes, they are heterozygous for eye color. They might have brown eyes, but they carry the gene for blue eyes as well.
