Gene vs. Genotype — What's the Difference?

In biology, a gene (from genos (Greek) meaning generation or birth or gender) is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein.During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits.

The genotype of an organism is its complete set of genetic material. However, the term is often used to refer to a single gene or set of genes, such as the genotype for eye color.

(in informal use) a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring

The genetic makeup, as distinguished from the physical appearance, of an organism or a group of organisms.

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.

The combination of alleles located on homologous chromosomes that determines a specific characteristic or trait.

(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.

A specific combination of alleles at one or more loci on a chromosome.

(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.

(genetics) The part (DNA sequence) of the genetic makeup of an organism which determines a specific characteristic (phenotype) of that organism.

(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;

A group of organisms having the same genetic constitution.

The type species of a genus; generitype.

(transitive) To determine the genotype of.

A group of organisms sharing a specific genetic constitution.

The genetic constitution of an organism, specifying the particular alleles at defined loci in the genome; - used with respect to one gene, a specific group of genes, or the entire set of genes within the organism. Contrasted with phenotype.

A group of organisms sharing a specific genetic constitution

The particular alleles at specified loci present in an organism
