Heterozygous
The state of having two different forms of a particular gene, one inherited from each parent. A person who is heterozygous is called a heterozygote or a gene carrier. For example, a woman who is heterozygous for cystic fibrosis (CF) carries the CF gene on one of her chromosomes number 7 and has the normal paired (non-CF) gene at the same position (locus) on her other chromosome 7. She is a carrier for CF but has no signs or symptoms of the disease. The opposite of heterozygous is homozygous, the inheritance of the same form of a gene from both parents.
