What is the phenotype of an individual with one allele dimples and one allele for no dimples

The phenotype of the individual is that he/she will have dimples.

A gene is a unit of inheritance located in the chromosomes. Usually, genes occur in pairs called alleles. Each pair of alleles control a certain trait.

In this case, let the gene for dimples be R and the gene for no dimple be r. The individual with one allele for dimples and one allele for no dimples will be Rr. Since the gene for dimples is dominant, it is expressed and the individual will have dimples.
