A heterozygous organism

Final answer:

Heterozygous organisms in biology carry two different alleles for a specific gene.

Step-by-step explanation:

In biology, when an organism has two different alleles for a specific gene, it is called heterozygous. This means that it carries both the dominant and recessive allele for that gene. Heterozygous organisms will have different genotypes but the same phenotype as homozygous dominant organisms. The recessive allele will only be observed in homozygous recessive individuals.

An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene.
