If the ability to roll one’s tongue is dominant (R) and the inability to roll one’s tongue is recessive (r), what are the possible genotypes for someone who can roll their tongue?

only RR

RR and Rr

RR and rr

only rr

Explanation:

100% correct answer is B

Since (R) is dominant allele, and (r) is recessive allele, the possible genotypes for someone who can roll their tongue would be:

B. RR and Rr.

What is a Dominant Allele?

A dominant allele is an allele that expresses itself even in the presence of a recessive allele.

For a dominant allele to express itself, it takes only a single copy of the allele to be present in a genotype.

Thus:

(R) is said to be dominant allele over a recessive allele (r) for tongue rolling.

Therefore, since (R) is dominant allele, and (r) is recessive allele, the possible genotypes for someone who can roll their tongue would be:

B. RR and Rr.
