Origin of alleleGerman allel from Classical Greek all?l?n, of one another
The definition of alleles are pairs or series of genes on a chromosome that determine the hereditary characteristics.
An example of an allele is the gene that determines hair color.
either of a pair of genes located at the same position on both members of a pair of chromosomes and conveying characters that are inherited in accordance with Mendelian law
Any of the alternative forms of a gene or other homologous DNA sequence. Also called allelomorph .
Origin of alleleGerman Allel short for Allelomorph allelomorph from English allelomorph
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. Complex traits such as height and longevity are usually caused by the interactions of numerous pairs of alleles, while simple traits such as eye color may be caused by just one pair.
