What is meant by the term dominant allele?

A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. In incomplete dominance, two dominant alleles can mix to create a third phenotype, a sort of mix between two phenotypes. ...

What is dominant and recessive allele?

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.

What is an example of a dominant allele?

Dominant alleles show their effect even if the individual only has one copy of the allele (also known as being heterozygous^?). For example, the allele for brown eyes is dominant, therefore you only need one copy of the 'brown eye' allele to have brown eyes (although, with two copies you will still have brown eyes).

What is the definition of recessive allele?

Definition. A type of allele that when present on its own will not affect the individual. Two copies of the allele need to be present for the phenotype to be expressed.

What are dominant traits in humans?

Human 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 allele means?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. ...

What traits are recessive?

Examples of 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.

What best describes a recessive allele?

The best description of a recessive allele is that in does not determine the phenotype when a dominant allele for the same trait is present.

Which allele is dominant color?

Black is dominant, which means black individuals must have at least one B allele. Their genotype could be either BB or Bb.
