Heterozygous

An organism that possesses different alleles in a gene is heterozygous.  It is an organism that carries different forms of a gene where those forms produce slightly different results (i.e., brown hair or black hair, blue eyes, or green eyes).  In each case, the same gene has slight variations, so they are different “hetero” forms of the same thing.
