The possible genotypes for someone who can roll their tongue are RR or rr, where the R allele is dominant over the r allele.

<h3>What do you mean by Genotypes?</h3>

Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for a particular study or interest.

If R represents the dominant allele and a person rolls their tongue having this allele, while the r represents the recessive allele and a person can not roll their tongue having this allele. To roll their tongue, a person needs only one dominant allele. Thus the person could have genotypes of RR or Rr.

Therefore, the possible genotypes for someone who can roll their tongue are RR or rr, where the R allele is dominant over the r allele.
