No because theres no selective advantage
tongue
There are different taste buds in our tongue. There is sweet at the front, salty at the middle, and bitter and sour all way further to the end of your tongue. So when we eat certain types of food, such as cucumber, which is sweet in our tongue, our other taste buds do not function yet but our sweet taste bud does.
If you bite the tongue hard enough to damage or sever the central muscle/ligament it will retract into the back of throat and choke you.
There is not an actual 'spicy' taste bud. When you get oils from a chilli pepper on you hands it starts to burn quickly, this is similar to what happens to your tongue. Capsaicin, the chemical that produces the sensation of spiciness is damaging some of the nerves at the surface of the tongue. Hence, someone who eats spicy food regularly will grow a tolerance for even spicier foods as the nerves on the tongue have become 'numb' to capsaicin.
The sublingual caruncle is found under your tongue (either side of the frenulum - the small folds going from your tongue and the cavity floor). This is where two salivary glands, the sublingual and submandibular glands, empty into the oral cavity. That is why saliva will sometimes spray out when you lift your tongue while yawning.
Tongue rolling is homozygous dominant and all issue from this pairing will be tongue rollers. This is the only result that is allowable with a standard Punnett square or branch diagram representation. T = tongue roller t = non-tongue roller TT X tt = 4 Tt ======With tongue rolling expressed.
A trait controlled by many genes
The expected frequency would be determined by calculating the probability of someone having both traits based on their individual frequencies in the population. This would involve multiplying the frequency of tongue rolling ability by the frequency of attached earlobes in the population. For example, if 70% of the population can tongue roll and 60% have attached earlobes, the expected frequency would be 0.70 x 0.60 = 0.42, or 42%.
Languages that do not require rolling the tongue include English, Mandarin Chinese, and Russian. These languages may be easier for individuals who struggle with rolling their tongue to learn.
Yes, there are statistics about tongue rolling. You can find these statistics online on websites like OMGFacts.com. Approximately 67 percent of females and 64 percent of males are able to roll their tongues.

a lickout.
no it is recessiveFamily studies clearly demonstrate that tongue rolling is not a simple genetic character, and twin studies demonstrate that it is influenced by both genetics and the environment. Despite this, tongue rolling is probably the most commonly used classroom example of a simple genetic trait in humans. Sturtevant (1965) said he was "embarrassed to see it listed in some current works as an established Mendelian case." You should not use tongue rolling to demonstrate basic genetics.No. Your mom is.
Tongue rolling ability is primarily genetic, meaning it is inherited and not something that can be learned or acquired. It is controlled by a single gene with two possible variations, determining whether an individual can roll their tongue or not.
