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, Examples, and Comparison to Homozygous
When you’re heterozygous for a specific gene, it means you have two different versions of that gene. Here's what that means.

Homozygous vs. Heterozygous: Definitions and Differences - Verywell Health
Generally speaking, there are three different possibilities: Someone is homozygous for the normal β-globin gene (has two normal copies). Someone is heterozygous (has one normal and one abnormal copy). Someone is homozygous for the abnormal β-globin gene (has two abnormal copies).

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 refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene. The relationship between the two alleles affects which traits are expressed.

Understand the Meaning of Heterozygous - ThoughtCo
In biology, heterozygous refers to having different alleles for a gene. Diploid organisms have two alleles for a gene that determine specific traits.

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.

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
Heterozygous. A diploid organism is heterozygous at a gene locus when its cells contain two different alleles (one wild-type allele and one mutant allele) of a gene. [3] . The cell or organism is called a heterozygote specifically for the allele in question, and therefore, heterozygosity refers to a specific genotype.

Homozygous vs. Heterozygous: What’s The Difference?
An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait. In plant and animal breeding, such organisms can be called homozygotes and heterozygotes.
