When the copies of a gene differ from each other, they are known as alleles. A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual.

Dec 20, 2023 · What is the difference between genes and alleles? Genes are segments of DNA that determine specific traits, while alleles are different versions of the same gene.

Aug 3, 2024 · A gene is a part of DNA that determines a trait, like hair or eye color. Alleles are versions of the same gene that can give traits different expressions, like hair color.

Mar 6, 2024 · The main difference between a gene and an allele is that a gene is a stretch of DNA or RNA that determines a specific trait, and an allele brings variations to a single trait.

Jun 20, 2025 · Genes and alleles are essential to basic genetics, but what are the differences between them? In this guide, we compare genes and alleles and provide simple definitions and examples for …

Aug 23, 2025 · A gene determines what trait will be expressed, such as hair color, while its alleles determine how that trait manifests, for instance, as brown, blonde, or red hair.

Nov 10, 2025 · Alleles determine the precise outcome of the general trait coded by the gene. For example, the gene for human hair texture exists, but specific alleles determine if the hair is straight, …

Jul 25, 2025 · Understanding the difference between a gene and an allele isn’t just for scientists—it’s a fascinating glimpse into how traits are passed down and how diversity thrives in nature.

A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene.

Sep 9, 2024 · Gene: Genes do not occur in pairs; each gene is a discrete segment of DNA. Allele: Alleles always occur in pairs for each gene, reflecting contributions from both parents.
