Gene vs. Trait: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 31, 2024
A gene is a segment of DNA encoding functional products; a trait is a characteristic or feature influenced by one or more genes.
Key Differences
Genes are units of heredity made up of DNA, residing in chromosomes, and responsible for guiding the formation of proteins or RNA. Traits, on the other hand, are the physical, behavioral, or physiological attributes that result from the expression of genes.
Genes carry the instructions for synthesizing proteins that determine how an organism’s body works and responds to its environment. Traits manifest as observable characteristics, such as eye color, which are influenced by the proteins produced as a result of genetic instructions.
In genetics, genes can be dominant or recessive, affecting the likelihood of a trait being passed to the next generation. Traits themselves are the manifestations of these genetic patterns, demonstrating how genetic information is expressed in an organism.
Genes undergo mutations, which can lead to variations in the way traits are expressed. These mutations in genes can lead to different versions of a trait, such as variations in hair color or susceptibility to certain diseases.
The study of genes is a central part of genetics, focusing on how genetic information is encoded and transmitted. The study of traits, conversely, involves understanding how these genetic instructions are manifested and can be observed in the phenotype of an organism.

Gene and Trait Definitions
Gene
Genes are units of hereditary information passed from parents to offspring.
Eye color is determined by multiple genes inherited from both parents.
Trait
Traits can be physical or behavioral characteristics influenced by genes.
Intelligence is a complex trait influenced by multiple genes.
Gene
Genes are responsible for guiding the development and functioning of organisms.
Genes play a crucial role in the growth and development of an organism.
Trait
Traits vary among individuals of the same species.
Different blood types are examples of genetic traits.
Gene
A gene is a segment of DNA that contains coding for a protein or RNA molecule.
The BRCA gene is associated with an increased risk of breast cancer.
Trait
A trait is a specific characteristic of an organism, like hair color or height.
Brown hair is a common trait in humans.
Gene
Genes can mutate, leading to variations in traits.
A mutation in the melanin gene can cause albinism.
Trait
Traits can be inherited or acquired through environmental factors.
Musical talent can be a trait developed through practice and genetic predisposition.
Gene
Genes are located on chromosomes and are made up of sequences of nucleotides.
The human genome contains about 20,000-25,000 genes.
Trait
Traits are the observable expression of genes.
The trait of blue eyes results from the expression of specific genes.
Gene
A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and is transcribed into an RNA molecule that may function directly or be translated into an amino acid chain. Genes undergo mutation when their DNA sequences change.
Trait
A distinguishing feature, as of a person's character.
Gene
(genetics) A theoretical unit of heredity of living organisms; a gene may take several values and in principle predetermines a precise trait of an organism's form (phenotype), such as hair color.
Trait
A morphological, physiological, or behavioral feature of an organism.
Gene
(molecular biology) A segment of DNA or RNA from a cell's or an organism's genome, that may take several forms and thus parameterizes a phenomenon, in general the structure of a protein; locus.
A change in a gene is reflected in the protein or RNA molecule that it codes for.
Trait
(Archaic) A short line or mark made with a writing or drawing implement.
Gene
(genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity;
Genes were formerly called factors
Trait
An identifying characteristic, habit or trend.
The number one personality trait I hate is hypocrisy. Why can't you be consistent!?
Trait
(object-oriented) An uninstantiable collection of methods that provides functionality to a class by using the class’s own interface.
Traits are somewhat between an interface and a mixin.
Trait
A stroke; a touch.
By this single trait Homer makes an essential difference between the Iliad and Odyssey.
Trait
A distinguishing or marked feature; a peculiarity; as, a trait of character.
Trait
A distinguishing feature of your personal nature
