(In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes). A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present. (In genetic terms, a recessive trait is one that is phenotypically expressed only in homozygotes).Mar 29, 2021
Examples of Dominant Traits 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.Apr 28, 2017
A dominant trait is expressed. when at least one gene in the pair is dominant. A recessive trait is expressed. when both genes in the pair are recessive.
A dominant trait is one which expresses or masks the other trait. In a genome, there are two opposing alleles of a gene, namely dominant and recessive. A dominant trait always expresses itself over a recessive trait, even if only one copy is present.
- Dominant trait is the first that appears or expressed visibly in the organism. For example- Baldness, Curly hair is dominant over straight hair etc. Dominant allele is expressed in capital letters like A versus a. Each parent provides one allele, the combinations are: AA, Aa, and aa.
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.Apr 12, 2021
dominant allele. an allele whose trait always shows up in the organism when the allele is present.
Examples of Recessive Traits Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits. Having round (as opposed to almond-shaped) eyes is recessive, along with inability to roll one's tongue.Apr 28, 2017
Dominant: form of an allele whose trait always shows up if it is present; recessive: form of an allele whose trait shows up only when the dominant allele is not present. You just studied 6 terms!
A dominant gene, or a dominant version of a gene, is a particular variant of a gene, which for a variety of reasons, expresses itself more strongly all by itself than any other version of the gene which the person is carrying, and, in this case, the recessive.
Definition. (genetics) An inherited trait that results from the expression of the dominant allele over the recessive allele. Supplement. The inheritance of one or two copies of the dominant alleles results in the expression of a dominant trait.Jan 19, 2021
Answer. The statement; It gives the same phenotype in heterozygotes and homozygotes is true for a dominant allele.
