<h3>What is a brief definition of alleles?</h3>
The phrase "allele" is utilized to refers to a gene's older form or variants. For each autosomal gene, one allele is inherited from every parent, and we often group the alleles in categories. Generally, we refers to them by their normal, wild-type, deviant, or mutant alleles.
<h3>What exactly are alleles and genes?</h3>
