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

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 and Examples - Biology Online
The term heterozygous is used to describe a cell, a nucleus, or an individual organism that carries different or non-identical alleles for a particular trait at the same loci on homologous chromosomes.

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.

Understand the Meaning of Heterozygous - ThoughtCo
In diploid organisms, a mutation that occurs on only one allele for a gene is called a heterozygous mutation. Identical mutations that occur on both alleles of the same gene are called homozygous mutations.

What Are Homozygous and Heterozygous Traits?
Two key terms used in understanding inherited traits are homozygous and heterozygous. These concepts describe the type of genetic information we inherit from our parents and how it influences our traits, characteristics, and even our risk of certain conditions.

Definition of heterozygous genotype - NCI Dictionary of Cancer Terms
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.

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.

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.
