There are two types of genetic traits: dominant and recessive. For example, the gene for having an extra finger is actually dominant, while the gene for having a tall stature is a recessive trait.
What are dominant traits in humans?
Human Dominant TraitsDark hair is dominant over blonde or red hair.Curly hair is dominant over straight hair.Baldness is a dominant trait.Having a widows peak (a V-shaped hairline) is dominant over having a straight hairline.Freckles, cleft chin and dimples are all examples of a dominant trait. •Apr 28, 2017
Why tallness is dominant?
A pea plant could have a copy of the height gene that coded for tall and a copy of the same gene that coded for short. But the tall allele is dominant, meaning that a tall-short allele combination would result in a tall plant.
Is there a gene for tallness in humans?
The first gene linked to tallness, one of the most heritable of traits, has been discovered by scientists, a finding that is expected to shed light on human development and further understanding of cancer.
Is height a dominant trait?
There are two types of genetic traits: dominant and recessive. When combined together in an offspring, the dominant trait will always be expressed over the recessive trait. For example, the gene for having an extra finger is actually dominant, while the gene for having a tall stature is a recessive trait.
What is meant by dominant 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.
Is a widows peak a dominant trait?
For example, the gene for hairline shape has two alleles – widows peak or straight. An individual may inherit two identical or two different alleles from their parents. For example, the allele for widows peak is dominant and the allele for straight hairline is recessive.
