Dominant trait (genetics) An inherited trait that results from the expression of the dominant allele over the recessive allele. The inheritance of one or two copies of the dominant alleles results in the expression of a dominant trait.

What is a Dominant Trait? A dominant trait is a genetic trait which will manifest when only one copy of the gene is present, overriding another inherited gene coding for a different version of the trait.By contrast, a recessive trait will only appear if an organism inherits a copy of the gene from both parents.n a simple example of the way in which dominant traits work, someone could have two parents who are heterozygous for brown and blue eyes. There is a 25% chance that the child will inherit the bb allele, making him or her blue-eyed.

- Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene.(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).Examples of dominant disorders include: 1  Achondroplasia (a common form of dwarfism with short arms and legs),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).

Dominant group/Synonymous definition Primordial hypothesis: dominant group is a primordial concept inherent to humans such that every language or other form of communication no matter how old or whether extinct, on the verge of extinction, or not, has at least a synonym for dominant group. Purpose hypothesis: dominant group is written into articles by authors for a purpose.

- Definition. Autosomal dominant is one of several ways that a trait or disorder can be passed down through families. If a disease is autosomal dominant, it means you only need to get the abnormal gene from one parent in order for you to inherit the disease. One of the parents may often have the disease.

dominant trait Dominant trait. A genetic trait in which one copy of the gene is sufficient to yield an outward display of the trait; dominant genes mask the presence of recessive genes; dominant traits can be inherited from a single parent.

Genetics Terms A characteristic that occurs when an allele's presence determines the phenotype of a heterozygous individual. For example, if T and t are two alleles of a gene, T is dominant if Tt individuals are phenotypically identical to TT individuals. characteristic that occurs when an allele's presence determines the phenotype of a heterozygous individual. For example, if T and t are two alleles of a gene, T is dominant if Tt individuals are phenotypically identical to TT individuals.

Dominant Trait: Definition & Example A recessive trait is the phenotype that is not seen in the heterozygous genotype, and attached earlobes are a recessive trait. This brings us back to our main topic, which we can now define. A dominant trait is the phenotype that is seen when the heterozygous genotype is present.efore we can define exactly what a dominant trait is, we must first define and discuss many genetics terms. A gene, or unit of heredity, can have many different versions called alleles.

Dominant Trait: Definition & Example Definition of Dominant Trait. Before we can define exactly what a dominant trait is, we must first define and discuss many genetics terms. A gene, or unit of heredity, can have many different versions called alleles. There are often two kinds of alleles: Dominant allele: masks the effects of another allele; designated by an uppercase letter ; Recessive allele: effects are hidden by a dominant allele; designated by a lowercase letter ; Normally, individuals have two alleles for one gene: one from their mom and one from their dad.

What does dominant mean in science? Dominant in science means either 'expressed' in genetic terms or 'widely held and accepted as the basis of comparison' in general terms such as the dominant view.

Homozygous Dominant: Definition & Example Definition of Homozygous Dominant. Many genes come in two versions: the dominant allele and the recessive allele. Since diploid organisms (like you and me) have two copies of each of our genes, we could have one of each allele and be heterozygous or have two of the same and be homozygous.f a cat (or a person, or a pea plant) has two dominant alleles of a certain gene, we say it is homozygous dominant for that particular trait.

Dominance (genetics) Dominance (genetics) Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive. For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics.

Dominant Culture in America A dominant culture is one that is able through economic or political power, to impose its values, language and ways of behaving on a subordinate culture or cultures.

Biology Set 2 1 If both alleles are dominant, it is called codominance. 2  The resulting characteristic is due to both alleles being expressed equally. 3  An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles.

Autosomal dominant Definition. Autosomal dominant is one of several ways that a trait or disorder can be passed down (inherited) through families. In an autosomal dominant disease, if you inherit the abnormal gene from only one parent, you can get the disease.Often, one of the parents may also have the disease.t also depends on whether the trait is dominant or recessive. A single abnormal gene on one of the first 22 nonsex (autosomal) chromosomes from either parent can cause an autosomal disorder.

Gene dominant gene one that produces an effect (the phenotype) in the organism regardless of the state of the corresponding allele. An example of a trait determined by a dominant gene is brown eye color.See also heredity. histocompatibility gene one that determines the specificity of tissue antigenicity (hla antigens) and thus the compatibility of donor and recipient in tissue transplantation and blood transfusion.n example of a trait determined by a dominant gene is brown eye color.

dominant trait an inherited characteristic that is determined by a dominant allele. Polydactyly is an example of a dominant trait; individuals with either one or two copies of the polydactyly allele have extra fingers or toes.

What is dominant allele? A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a domi … nant allele over a recessive allele. The dominant allele is expressed over the recessive allele.f the two dominant alleles are different, it is called  co-dominance. Another name for two dominant alleles that are  different is Incomplete dominance.

Dominance (genetics) Alleles are dominant or recessive, meaning: 1  the characteristic controlled by a dominant allele develops if the allele is present on one or both chromosomes in a pair. 2  the characteristic controlled by a recessive allele develops only if the allele is present on both chromosomes in a pair.lleles are dominant or recessive, meaning: 1  the characteristic controlled by a dominant allele develops if the allele is present on one or both chromosomes in a pair. 2  the characteristic controlled by a recessive allele develops only if the allele is present on both chromosomes in a pair.

dominant (dŏm'ə-nənt) Relating to the form of a gene that expresses a trait, such as hair color, in an individual organism. The dominant form of a gene overpowers the counterpart, or recessive, form located on the other of a pair of chromosomes. Relating to the trait expressed by such a gene. See more at inheritance. Compare recessive.
