Heterozygous: Definition, Examples, and Comparison to Homozygous
When you’re heterozygous for a specific gene, it means you have two different versions of that gene. The dominant form can completely mask the recessive one, or they can blend together.
Heterozygous - National Human Genome Research Institute
Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker.
Heterozygous Genotype: Traits and Diseases - Verywell Health
Heterozygous genotypes occur when two different versions of a gene, known as alleles, appear at the same location on a pair of chromosomes. Heterozygosity plays a key role in dominant-recessive traits and the inheritance patterns of genetic conditions.
What Is Heterozygous and Homozygous in Genetics?
Homozygous means you carry two identical copies of a gene variant, while heterozygous means you carry two different copies. Since you inherit one copy from each parent, every gene in your body exists as a pair. Whether those two copies match or differ determines your “zygosity,” which in turn shapes which traits show up and which stay hidden.
Zygosity - Wikipedia
The words homozygous, heterozygous, and hemizygous are used to describe the genotype of a diploid organism at a single locus on the DNA.
HETEROZYGOUS Definition & Meaning - Merriam-Webster
The meaning of HETEROZYGOUS is having the two alleles at corresponding loci on homologous chromosomes different for one or more loci. How to use heterozygous in a sentence.

Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker.
Homozygous vs. Heterozygous Genes - Verywell Health
If you have two copies of the same version of a gene, you are homozygous for that gene. If you have two different versions of a gene, you are heterozygous for that gene.
What Does Heterozygous Mean in Genetics? - Biology Insights
The term “heterozygous” literally means having different components, which in genetics refers to having two dissimilar alleles for a particular gene. An individual with a heterozygous genotype has inherited one version of a gene from one parent and a different version from the other parent.
Heterozygous: Meaning and Genetic Health | Acibadem Health Point
Heterozygous describes a person who has two different versions of a gene, one inherited from each parent. In many cases it has no health impact, but in some genetic conditions it can influence disease risk, carrier status, or symptoms.
