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.

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: 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 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, homozygosity is when there are two copies of the same allele at the same locus.

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.

Homozygous vs. Heterozygous: What's the Difference?
Learn the difference between homozygous vs. heterozygous with simple explanations and clear examples. Understand how these genetics terms are used, their impact on traits, and how they shape inheritance.

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.
