An allele is a form of a gene that is responsible for a specific trait or characteristic. Each gene can have multiple alleles, which can be either dominant or recessive. Dominant alleles will always be expressed in an individual's phenotype, while recessive alleles will only be expressed if an individual has two copies of the recessive allele.
