are dimples dominant or recessive?

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.

Dimples are small indentations that can be found on your skin. They can occur on different places of the body, including the cheeks, chin, and lower back. Cheek dimples can be found on the sides of the mouth. You can have a dimple on both sides of your mouth or on just one side.

Dominance is not inherent to an allele or its traits (phenotype). It is a strictly relative effect between two alleles of a given gene of any function; one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth.

Some people have dimples in both cheeks, others in just one cheek. Babies are likely to have dimples caused by baby fat in their cheeks. When they lose their baby fat as they get older, their dimples disappear. Other children do not have them at birth, but may develop them later in childhood.

Dimples. ... "Some people have dimples that they mistake as smile lines, but the lines are really part of their dimple complex—especially if it seems like you have double parentheses right near the angle of your mouth." Which, she explains to us, is much harder to correct.

Figure 8-1. For a recessive mutation to give rise to a mutant phenotype in a diploid organism, both alleles must carry the mutation. However, one copy of a dominant mutant allele leads to a mutant phenotype. Recessive mutations result in a loss of function, whereas dominant (more...)

Is knuckle hair dominant or recessive? There is some debate about which genes carry the code for mid-phalangeal hair, but geneticists generally agree that it's a dominant trait.

What is the difference between the situations shown in the red and yellow lines? The red line shows a dominant allele; the yellow line shows a recessive allele.

The variant allele a is therefore described as recessive to the wild-type + allele (or, + is dominant to a; this may also be written a+ is dominant to a).

These factors ultimately decide whether the condition will be dominant or recessive in a child. In the dominant condition, the child is more likely to get type 1 diabetes due to a higher combination of defective genes received.

As nouns the difference between dimple and cleft is that dimple is a small depression or indentation in a surface while cleft is an opening, fissure, or v-shaped indentation made by or as if by splitting.

Broad brows are a dominant trait, while slender ones are recessive. If one or both parents have thicker brows, baby's will most likely follow suit.

What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.

Dominant traits are those traits which are expressed even in the presence of one copy of an allele for a particular trait in the gene. ... Recessive traits are those that are expressed only when two copies of an allele are present in the gene.

Well, to answer your question, only 20% of the population owns dimples which means that dimples are not common. The world's 20% of the population is only the one who can have dimples. ... Although dimples do look attractive yet medical science has proven that the dimples occur because of a genetic deformity.

But no one ever says what causes an allele to be dominant or recessive. Part of the reason no one talks about this is that there's no one-size-fits-all answer. Different alleles can be dominant or recessive for different reasons. It all depends on the gene.

In additive hereditary, genes and alleles "add up" to influence the phenotype. In dominant-recessive heredity, one allele is more influential than the other and thus controls the expression of a characteristic even when a recessive gene is the other half of a pair.
