An organism with two different alleles of a gene.
An organism with two identical alleles of a gene.

The term used to describe the specific location of a gene/DNA sequence on a chromosome; variations of these genes are referred to as alleles.
An observable characteristic of someone’s traits, examples: eye color, skin color, height, gender etc.
