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.
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.
How nice you are. Yeah I was shocked too when I found out.
Some examples of discrete traits include blood type (A, B, AB, O), fingerprints patterns (loop, whorl, arch), and tongue rolling ability (can roll tongue or cannot roll tongue). These traits have distinct categories or options with no intermediate forms.

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.

The ability to fold your tongue, known as tongue rolling or cloverleaf tongue, is a genetic trait. It is determined by a dominant gene, meaning you only need one copy from either parent to be able to do it. Not everyone can fold their tongue, as it varies among individuals based on their genetic makeup.

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.
The expected frequency can be calculated using the product rule in probability. If we assume that the ability to roll the tongue and having attached earlobes are independent, then we can multiply the frequencies of each trait in the population to get the expected frequency of individuals with both traits.
a lickout.
