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.
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.
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, Usage & Quiz | UltimateLexicon.com
Heterozygous refers to an organism that has two different alleles for a specific gene. In heterozygous pairings, one allele is typically dominant while the other is recessive.
Heterozygous - Definition, Types, Inheritance, Clinical Significance
In genetics, an allele is a variant form of a gene found at a specific locus on a chromosome. An individual inherits one allele from each parent. A heterozygous individual has two different alleles for a particular gene, unlike a homozygous individual who has identical alleles.
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.
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 Gene - Understanding the Role and Implications
Heterozygous gene refers to the presence of two different alleles for a particular gene, leading to variations in traits and genetic diversity.
