Can a child have dimples if neither parent does?

Facial dimples are genetically inherited. Since his dad also has dimples, it was pretty much a surefire outcome. Since dimples are a dominant trait, only one parent needs to have them.

Are dimples incomplete dominance?

Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples.

What creates dimples?

Dimples are sometimes caused by a change in a facial muscle called the zygomaticus major. This muscle is involved in facial expression. It’s the one that helps to raise the corners of your mouth when you smile. Movement of the skin over the double zygomaticus major muscle when you smile causes the dimple to form.

Do dimples get deeper when you lose weight?

As I gained weight, the dimple almost disappeared. If you keep eating healthy, it probably will get more defined. Dimples are due to presence of heat in body . So if u loose weight and drink sufficient lukeworm clean water with proper diet your dimples definately go away.

What percentage of the offspring will have dimples?

The cross will be Dd x dd. There is a 50\% chance that the child does not obtain the allele needed for dimples (dd), and a 50\% chance that the child is heterozygous (Dd). Because dimples is an autosomal dominant trait, heterozygosity will express dimples, leading to a 50\% chance that the child will have dimples.

Are dimples dominate or recessive genes?

Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples. However, some researchers say that there is no proof that dimples are inherited. Little research has been done to explore the genetics of dimples and it is not known which gene or genes may be involved.

Are curly ears a dominant or recessive trait?

Since your problem states that all the offspring have the same phenotype, the correct Punnett square is the first one where all the kittens are heterozygous (Ee). Since the dominant allele (E) masks the recessive allele (e), then curly ears has to be the dominant trait, since that’s the phenotype of all the kittens.

Is thalassemia a dominant trait?

Most thalassemias are inherited as recessive traits. Thalassemia is autosomal dominant in a very small percentage of beta thalassemia cases. A person who has only one mutated or defective gene typically does not experience symptoms and is called a carrier (thalassemia trait or thalassemia minor).

What genes are dominate for Cheek dimples?

What gene is responsible for dimples? It is believed that cheek dimple genes occur on the 16th chromosome, whereas cleft chin genes occur on the 5th. However, the University of Utah considers dimples an “irregular” dominant trait that is probably controlled mostly by one gene but is influenced by other genes.
