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.

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 Definition & Meaning | Dictionary.com
HETEROZYGOUS definition: relating to or being a heterozygote, an organism that possesses a pair of differing alleles, one dominant and one recessive, of a particular 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 Genotypes: How They Affect Traits (With Examples)
Heterozygous individuals are carriers of recessive traits, which may surface in offspring. Examples include sickle cell trait (heterozygous HbA/HbS) and flower color in pea plants. Heterozygosity plays a role in disease resistance (e.g., malaria protection) and agricultural breeding. 🧬 What Is a Heterozygous Genotype?

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.

Heterozygote | biology | Britannica
In a heterozygous organism, or heterozygote, the genes for a specific trait are different.

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.

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.
