First of all, the inability to roll your R's is not genetic, it is a skill that is acquired through practice. And it has nothing to do with rolling your tongue.
Haplogroup R-M512 is a genetic marker that is associated with the migration of early humans out of Africa and into Europe. It is believed to have originated in the Middle East around 20,000 years ago and is found in a significant portion of European populations today. This haplogroup provides insights into the genetic ancestry and migration patterns of human populations.
The R-M512 haplogroup is significant in human genetic ancestry as it is a branch of the R1b haplogroup, which is one of the most common paternal lineages in Western Europe. This haplogroup is believed to have originated in the Near East and spread into Europe during the Neolithic period, playing a key role in the genetic history of many European populations.

The process is called transformation, and it was the first direct evidence that genetic information could be transferred between bacteria. In Griffith's experiment, the heat-killed S strain released its genetic material, which was then taken up by the live R strain, converting it into the deadly S strain.
In classic genetics: AA or Aa for autosomal dominance; for sex-linked dominance, females will need XX or Xx, while males will need Xy It gets more complicated with epistasis and other factors that modulate the genes.
In some cases yes in others no. It's possible to grow out of not being able to roll an R.
The ability to roll one's tongue is a trait influenced by a dominant allele (R) and a recessive allele (r). The male with genotype Rr can pass on either the R or r allele, while the female with genotype rr can only pass on the r allele. Therefore, their children could inherit either Rr (able to roll their tongue) or rr (unable to roll their tongue), resulting in a 50% chance of having the ability to roll their tongues.
Crazily addicted to r and r. Other wise known as rotate and roll.
U R N 0:) means: You Are No Angel. The 0:) being the angel. Or how about You are number one

Siarra(roll the "r's"
You have to roll the 'R'.

eegra -when you say it you should roll your tongue when you say the r like how spanish people roll their tongue when they say r's.
There are several kinds of French; there is Parisian French from Paris, Quebec French from Quebec Canada, and French in the New Orleans area. None of these dialects need to roll the r. However, at least in Parisian French, you do have to do a "special" r, made by having the tip of the tongue on the bottom of the mouth, and arced so the middle is close to the top. It's sort of a "phlegm-y" sound, not sounding like a rolled or normal English r. It is known as "guttural R", and is used in French, Portuguese, and Dutch. Spanish and Italian (but also Indonesian) feature the so-called trilled R.
