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

The phenotype of an individual with one allele for no dimples will typically be determined by the dominance of the allele. If the allele for no dimples is dominant, the individual will express the no dimples trait. However, if the allele for dimples is dominant, the individual may still have dimples despite having one allele for no dimples. Thus, the specific phenotype will depend on the dominance relationship between the alleles involved.
