The ability to roll one's tongue and to cross one's fingers are both inherited traits, meaning they are determined by our genes. However, it is important to note that not everyone can perform these actions, as they are not universal.

Tongue rolling:

The ability to roll one's tongue is influenced by genetics. It is believed to be determined by a single gene with two alleles: the dominant allele "R" for the ability to roll the tongue, and the recessive allele "r" for the inability to roll the tongue. If you inherit at least one "R" allele from either of your parents, you will likely possess the ability to roll your tongue. On the other hand, if you inherit two "r" alleles, you will not be able to perform this action. So, whether you can roll your tongue or not is determined by the combination of these alleles.

Finger crossing:

The ability to cross one's fingers is not controlled by a single gene like tongue rolling. It is a more complex trait influenced by various genes and genetic factors. It is also influenced by individual flexibility and dexterity, which can vary among people. While there may be some genetic predisposition for finger crossing, it is difficult to attribute this trait solely to genes.

In conclusion, tongue rolling is influenced by a single gene, while finger crossing is a more complex trait influenced by several genes and individual factors.
