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 is a term used in genetics to describe when two variations of a gene, known as alleles, are paired at the same location (locus) on a chromosome. By contrast, homozygous is when there are two copies of the same allele at the same locus.

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 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.

What Is the Definition of Heterozygous? - Biology Insights
The term heterozygous describes a genotype where an individual has inherited two different alleles for a specific gene. For example, if a person inherits the allele for brown eyes from one parent and the allele for blue eyes from the other, they are heterozygous for that eye color gene.

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.

Definition of heterozygous genotype - NCI Dictionary of ...
A term that describes having two different versions of the same gene (one inherited from the mother and one inherited from the father). In a heterozygous genotype, each gene may have a different mutation (change) or one of the genes may be mutated and the other one is normal.
