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

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 Heterozygosity? Definition and Significance
If both parents are heterozygous for a trait, each has a 50% chance of passing on either their dominant or recessive allele to offspring. This allows offspring to be homozygous dominant, homozygous recessive, or heterozygous, with specific probabilities.

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 - Definition and Examples | Biology Dictionary
Heterozygous is a description of the genotype, or combination of alleles present in an organism. The genotype gives rise to the phenotype. Depending on the different relationships between alleles, different phenotypes are created in a heterozygous individual.

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.

What is Heterozygous in biology? - California Learning Resource Network
In the realm of genetics, heterozygous describes a fundamental genotypic state where an organism possesses two different alleles for a particular gene locus on homologous chromosomes. This contrasts with the homozygous state, characterized by the presence of identical alleles at the same locus.
