Compare with Definitions
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.
Allele
An allele (UK: , ; US: ; modern formation from Greek ἄλλος állos, "other") 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.
Gene
(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
Playing tennis is in my genes
Allele
Any of the alternative forms of a gene or other homologous DNA sequence. Also called allelomorph.
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.

Allele
(genetics) One of a number of alternative forms of the same gene occupying a given position, or locus, on a chromosome.
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.
Allele
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.
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.
Allele
Either of a pair of Mendelian characters that may occur in an organism as a consequence of variation at one gene locus.
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
Allele
One of two alternate forms of a gene that can have the same locus on homologous chromosomes and are responsible for alternative traits;
Some alleles are dominant over others
