What is the genotype of a heterozygous person with a cleft chin?

Cc

Explanation:

A cleft chin is an example of a trait that is controlled by genetics. A cleft chin is when there is a dimple in the chin which arises when the two sides of the jaw don’t completely fuse together. Famous people with cleft chins are Henry Cavill, John Travolta and Niall Horan.

A cleft chin is generally thought to be a dominant trait. That means, if an individual carries one copy of the cleft chin gene (heterozygous), then they will display the trait.

There are three options: an individual can be homozygous dominant (CC), homozygous recessive (cc) or heterozygous (Cc). A heterozygous person will always have 2 different alleles (for any trait, not just cleft chin). In this case, a heterozygous person will have a cleft chin, because it is dominant. Therefore, an heterozygous person with a cleft chin will be Cc

Remember, the letter doesn't matter - they could also be denoted as Bb, Qq, Rr, Ff. The letter is arbitrary.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.
