An organism that has two different alleles for a particular trait is indeed considered heterozygous for that trait.

Here's a breakdown:

* Allele: A specific version of a gene.

* Heterozygous: Having two different alleles for a trait.

* Homozygous: Having two identical alleles for a trait.

For example, let's say a gene controls flower color, and there are two alleles:

* R: Red flower

* r: White flower

An organism with the genotype Rr would be heterozygous for flower color because it has one red allele (R) and one white allele (r).
