Alleles refer to alternative forms of a gene that arise by mutation and are located at the same position on homologous chromosomes. They determine the genotype of an individual organism with respect to a particular character, which can be dominant or recessive. In the context of the hierarchy "Science/Genetics/Mutation/Alleles," alleles represent the specific genetic variations resulting from mutations within genes. These alterations contribute to genetic diversity and may influence phenotypic traits, thus playing a crucial role in genetics and evolutionary biology.
