Gene vs. Allele

Genenoun

(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.

Genenoun

(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.

Genenoun

(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;

Genenoun

(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

Genenoun

(in technical use) a distinct sequence of nucleotides forming part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid molecule which a cell (or virus) may synthesize.

Gene

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.

Allelenoun

(genetics) One of a number of alternative forms of the same gene occupying a given position, or locus, on a chromosome.

Allelenoun

one of two or more alternative forms of a gene that can have the same place on homologous chromosomes and are responsible for alternative traits.

Allelenoun

either of a pair of Mendelian characters that may occur in an organism as a consequence of variation at one gene locus.

Allelenoun

one of two alternate forms of a gene that can have the same locus on homologous chromosomes and are responsible for alternative traits;

Allele

An allele (UK: , ; US: ; modern formation from Greek ἄλλος állos, ) is one of two, or more, forms of a given gene variant. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles.
