It is heredity. Not everyone has the necessary gene.

It's a dominant gene to roll your tongue. So if one parent is able to roll his/her tongue there is a higher chance of being able to roll your tongue.

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 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. 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.


Is tongue rolling an acquired ability?

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.


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.

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 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.
