No organism has all dominant or all recessive genes
. An organism may be pure in certain traits and hybrid others. Remember, that a dominant trait in one kind of organism may be a recessive trait in another organism. 1.
Are there always more dominant traits in an individual?
Whether an allele is dominant or not does not affect how common a trait is. Now of course traits can become more
common
over time. The changes just don’t have anything to do with whether the trait is dominant or not. If brown eyes gave an advantage, then it would start to become more common.
Can a dominant trait be rare?
Some dominant genes are rare, meaning that a small subset of humans have the dominant allele. The
polydactyly trait — having extra fingers or toes —
is one example of a rare inherited dominant gene trait.
Is being dominant a trait?
Dominant: A genetic trait is considered dominant
if it is expressed in a person who has only one copy of that gene
. … A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present.
How many dominant genes does it take to show the trait?
That is, both loci must have at
least one dominant allele
to produce the phenotype.
Is having dimples a dominant or recessive trait?
Dimples—indentations on the cheeks—tend to occur in families, and this trait is assumed to be inherited. 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 traits are dominant in humans?
- Dark hair is dominant over blonde or red hair.
- Curly hair is dominant over straight hair.
- Baldness is a dominant trait.
- Having a widow’s peak (a V-shaped hairline) is dominant over having a straight hairline.
- Freckles, cleft chin and dimples are all examples of a dominant trait.
Which best defines a dominant trait?
Dominant: A genetic trait is considered dominant
if it is expressed in a person who has only one copy of that gene

What traits are inherited?
Inherited traits include things such as
hair color, eye color, muscle structure, bone structure
, and even features like the shape of a nose. Inheritable traits are traits that get passed down from generation to the next generation. This might include things like passing red hair down in a family.
Is curly hair a dominant trait?
Curly hair is
considered a “dominant” gene trait
. Straight hair is considered “recessive.” To put that in simple terms, that means that if one parent gives you two curly haired genes and the other parent gives you a pair of straight-haired genes, you’ll be born with curly hair.
How can you tell if a trait is dominant or recessive?
For example, if a trait tends to be directly passed from parent to child, then
the odds are pretty good that the trait is
a dominant one. If a trait skips generations or pops up out of nowhere, then the odds are pretty good that it is recessive.
Do dimples come from Mom or Dad?
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. If you or your partner has dimples, there is an over 50% chance your baby will have them.
What is the rarest dimple?
In what researchers called “a rare phenomenon,” it’s possible that a person can possess a unilateral dimple: just one lone dimple on either the left or right side of his or her face. Even rarer than this sort of dimple, though, is the
“fovea inferior angle oris”
— aka one dimple on each side of the mouth corners.
Is a dimples a disorder?
Because cheek dimples can result from a muscular variation that occurs during fetal development, they’re sometimes mistakenly referred to as a
birth defect
. It’s important to remember that not only are cheek dimples rather common, but they also don’t have any negative health effects.
