Alleles can come in different extremes of size. At the lowest possible size an allele can be a single nucleotide polymorphism SNP.

However, sometimes, different alleles can result in different observable phenotypic traits , such as different pigmentation.

A notable example of this is Gregor Mendel's discovery that the white and purple flower colors in pea plants were the result of "pure line" traits, that is a single gene with two alleles.

All multicellular organisms have two sets of chromosomes at some point in their life cycle ; that is, they are diploid. In this case, the chromosomes can be paired.

Each chromosome in the pair contains the same genes in the same order, and place, along the length of the chromosome.

For a given gene , if the two chromosomes contain the same allele, they, and the organism, are homozygous with respect to that gene.

If the alleles are different, they, and the organism, are heterozygous with respect to that gene. The word "allele" is a short form of allelomorph "other form", a word coined by British geneticists William Bateson and Edith Rebecca Saunders , [10] [11] which was used in the early days of genetics to describe variant forms of a gene detected as different phenotypes.

In many cases, genotypic interactions between the two alleles at a locus can be described as dominant or recessive , according to which of the two homozygous phenotypes the heterozygote most resembles.

Where the heterozygote is indistinguishable from one of the homozygotes, the allele expressed is the one that leads to the "dominant" phenotype, [12] and the other allele is said to be "recessive".

The degree and pattern of dominance varies among loci. This type of interaction was first formally described by Gregor Mendel.

However, many traits defy this simple categorization and the phenotypes are modeled by co-dominance and polygenic inheritance.

The term " wild type " allele is sometimes used to describe an allele that is thought to contribute to the typical phenotypic character as seen in "wild" populations of organisms, such as fruit flies Drosophila melanogaster.

Such a "wild type" allele was historically regarded as leading to a dominant overpowering - always expressed , common, and normal phenotype, in contrast to " mutant " alleles that lead to recessive, rare, and frequently deleterious phenotypes.

It was formerly thought that most individuals were homozygous for the "wild type" allele at most gene loci, and that any alternative "mutant" allele was found in homozygous form in a small minority of "affected" individuals, often as genetic diseases , and more frequently in heterozygous form in " carriers " for the mutant allele.

It is now appreciated that most or all gene loci are highly polymorphic, with multiple alleles, whose frequencies vary from population to population, and that a great deal of genetic variation is hidden in the form of alleles that do not produce obvious phenotypic differences.

A population or species of organisms typically includes multiple alleles at each locus among various individuals.

Allelic variation at a locus is measurable as the number of alleles polymorphism present, or the proportion of heterozygotes in the population.

A null allele is a gene variant that lacks the gene's normal function because it either is not expressed, or the expressed protein is inactive.

For example, at the gene locus for the ABO blood type carbohydrate antigens in humans, [13] classical genetics recognizes three alleles, I A , I B , and i, which determine compatibility of blood transfusions.

It is now known that each of the A, B, and O alleles is actually a class of multiple alleles with different DNA sequences that produce proteins with identical properties: more than 70 alleles are known at the ABO locus.

The frequency of alleles in a diploid population can be used to predict the frequencies of the corresponding genotypes see Hardy—Weinberg principle.

Example sentences from the Web for allele Our current understanding of natural selection is that it operates as a ratio, with the numerator reflecting the success of genes in projecting copies of themselves into the future and the denominator, the success of alternative allele s.

Barash August 19, Nautilus. Derived forms of allele allelic , adjective allelism , noun. One member of a pair or series of genes that occupies a specific position on a specific chromosome.

Published by Houghton Mifflin Company. Any of the possible forms in which a gene for a specific trait can occur. Also, some traits are controlled by two or more gene sites.

Both possibilities multiply the number of alleles involved. All genetic traits are the result of the interactions of alleles. Mutation , crossing over, and environmental conditions selectively change the frequency of phenotypes and thus their alleles within a population.

For example, alleles that are carried by individuals with high fitness meaning they successfully reproduce and pass their genes to their offspring have a higher likelihood of persisting in a population than alleles carried by less-fit individuals, which are gradually lost from the population over time.

Published by Houghton Mifflin Company. Any of the possible forms in which a gene for a specific trait can occur. In almost all animal cells, two alleles for each gene are inherited, one from each parent.

Paired alleles one on each of two paired chromosomes that are the same are called homozygous , and those that are different are called heterozygous.

In heterozygous pairings, one allele is usually dominant, and the other recessive. For example, alleles that are carried by individuals with high fitness meaning they successfully reproduce and pass their genes to their offspring have a higher likelihood of persisting in a population than alleles carried by less-fit individuals, which are gradually lost from the population over time.

Thus, in the United States the M allele occurs in people of European descent with a frequency of 0. If alternative alleles alternative DNA sequences have identical fitness—if they are identically able to perform their function—changes in allelic frequency from generation to generation will occur only by genetic drift.

Rates of allelic substitution will be stochastically constant—that is, they will occur with a constant probability for….

For example, in the case of the first gene, in the ancestral population all alleles are A , and in the evolved population all are a.
