That said, having detached earlobes, a widow's peak, mid-digit hair and a straight thumb are generally considered to be dominant traits, although clearly their inheritance is complex. A dominant trait is one that only needs one copy of the dominant allele to be displayed.Jun 13, 2013

What are common dominant traits?
Examples of Dominant Traits
- 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.
What are 5 common inherited human traits?
Inherited Traits Examples
- Tongue rolling.
- Earlobe attachment.
- Dimples.
- Curly hair.
- Freckles.
- Handedness.
- Hairline shape.
- Green/Red Colourblindness.
What are the examples of family traits?
Hairline shape, hair color, and freckles are examples of family traits. A family tendency is a genetic trait.
What are 10 recessive traits?
Gene expression determines our phenotype. Some of these genes (dominant) mask the effect of others (recessive)….Single Gene Traits.
| Traits | Dominant | Recessive |
|---|---|---|
| Hairline | Widow's peak | Straight |
| Hair color | White hair streak | Normal hair color |
| Handedness | Right handedness | Left handedness |
| Hitchhiker's thumbs | Absence | Presence |
Are brown eyes dominant?
The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive. Given this information, you can determine what eye colors are dominant in the parents.
What are some examples of dominant and recessive traits?
For example, having a straight hairline is recessive, while having a widow's peak (a V-shaped hairline near the forehead) is dominant. Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits.
Is 6 fingers a dominant trait?
Polydactyly Polydactyly is an abnormality characterized by extra fingers or toes. The condition may be present as part of a collection of abnormalities, or it may exist by itself. When polydactyly exhibits by itself, it is inherited as an autosomal dominant trait.
What are dominant genetic traits?
An allele of a gene is said to be dominant when it effectively overrules the other (recessive) allele. Eye colour and blood groups are both examples of dominant/recessive gene relationships.
What are dominant recessive traits?
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
