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.

What is a trait controlled by only one gene?
How nice you are. Yeah I was shocked too when I found out.
Why is tongue folding dominant?
The ability to fold the tongue is not necessarily a dominant genetic trait. It is largely determined by the specific combination of genes inherited from both parents, known as a polygenic trait. Some people may have inherited a combination of genes that makes tongue folding easier for them, while others may not have this trait even if their parents do.
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.
Suppose an individual is heterozygous for both traits tongue rolling and cleft chin what is their genotype?
The genotype for an individual who is heterozygous for both traits of tongue rolling and cleft chin would be RrCc. "R" represents the dominant allele for tongue rolling and "r" represents the recessive allele for non-tongue rolling, while "C" represents the dominant allele for cleft chin and "c" represents the recessive allele for no cleft chin.
What does it mean that an organism is homozygous dominant for a trait?
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
Which is a mendelian trait?
A trait controlled by many genes
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 difference between a dominant trait and a recessive trait?
A dominate trait will most likely take over the recessive.
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 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.
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.
Is being able to roll your tongue a dominant or a recessive trait?
Being able to roll your tongue is dominant, not being able to is recessive. Therefore, if you can roll your tongue, you have either a homozygous dominant gene for being able to roll your tongue, or a heterozygous gene. If you cannot, then you have a homozygous recessive gene.

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.
