Thank you for the opportunity to help you with your question!
allele is a variant form of a gene.
Some genes have a variety of different
forms, which are located at the same position, or genetic locus, on a chromosome.
Humans have two alleles at each
genetic locus, with one allele inherited from each parent. Each pair of alleles
represents the genotype of a specific gene.. When the alleles of a pair are heterozygous, one may be dominant and the other recessive. The dominant allele is expressed and the recessive allele is masked.
Please let me know if you need any clarification. I'm always happy to answer your questions.
