no it is recessive
Family 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.

Which is a mendelian trait?
A trait controlled by many genes
Is it possible for two tongue rolling parents to have non tongue rolling baby?
Yes, it is possible for two tongue-rolling parents to have a non-tongue-rolling baby. Tongue rolling is often considered a genetic trait, typically associated with a dominant allele. However, if both parents carry a recessive allele for non-tongue rolling, there is a chance they could pass that trait to their child, resulting in a non-tongue-rolling offspring.
What is the letter form in dominant and recessive trait?
It depends on what your trait is. Let's say that your trait was tongue roller. Rolling your tongue is dominant over non-tongue rollers so we would use R for Rolling your tongue. For the recessive trait, non-tongue roller, we use the same letter as the dominant trait except it is lowercase. So non-tongue roller would be r.
What is the definition of a discrete trait?
A discrete trait is a trait which doesn't have a range of phenotypes. For example, tongue rolling is a discrete trait as an individual can either roll their tongue or not roll their tongue. There is no phenotype between these two phenotypes.
Is tongue rolling a dominant trait?
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.

What does it mean if you can roll your tongue?
The ability to roll your tongue is a genetically inherited trait. Some people can do it, and others can't. If you can roll your tongue, it simply means that you have inherited that trait. If you can't, then you lack it. It's genetic, and out of your control.
What is a trait controlled by only one gene?
How nice you are. Yeah I was shocked too when I found out.
What does being able to roll your tongue mean?
Being able to roll your tongue is a genetic trait controlled by a single gene with two alleles. If you can roll your tongue, you are likely to have inherited the dominant allele for tongue rolling. If you cannot roll your tongue, you likely have inherited the recessive allele.
How do genes affect tongue rolling?
Tongue rolling is a trait influenced by genetics, primarily determined by a single gene with two alleles: one for the ability to roll the tongue (dominant) and one for the inability to do so (recessive). Individuals who inherit at least one dominant allele from their parents can roll their tongues, while those with two recessive alleles cannot. This trait is often used as a classic example in genetics to illustrate inheritance patterns. However, environmental factors and other genetic influences can also play a role in the expression of this trait.
When a tongue rolling man has a baby to a non tongue rolling women all the babies are tongue rollers explain why this occurs?
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.
Is there a relationship between the frequency of a trait in a population and whether that trait is dominant or recessive?
Some observable traits in humans are dimples, earlobes, tongue-rolling, cleft chin, hairline, and freckles. The relationship between the frequency of a trait in a population and whether the trait is dominant or recessive because in inherited human traits, the offspring can either have dimples or no dimples.
Is rolling your tongue a learned behavior?
Rolling your tongue is a genetic trait influenced by a specific gene. It is not a learned behavior, but rather a characteristic that some people inherit and some do not, depending on their genetic makeup.
