<h3>Gene Allele </h3>
An allele in genetic studies is an alternative gene form that is located at a particular point of the chromosome. It is usually represented with capital and small letter of the same alphabet.
There are two types of a allele which include:
Dominant allele: This is when the variation seen in a gene produces a noticeable phenotype. This is seen in the gene combination of HH.
Recessive allele: This type of allele does not produce any visible noticeable phenotype. This is seen in hh.
