Recessive Trait: Definition & Example A recessive trait is the phenotype that is seen only when a homozygous recessive genotype for the trait of interest is present. This means that an individual must have two recessive alleles for the gene that determines this trait of interest.

Medical Definition of Recessive, autosomal Autosomal recessive: A genetic condition that appears only in individuals who have received two copies of an autosomal gene, one copy from each parent.The gene is on an autosome, a nonsex chromosome.The parents are carriers who have only one copy of the gene and do not exhibit the trait because the gene is recessive to its normal counterpart gene.utosomal recessive: A genetic condition that appears only in individuals who have received two copies of an autosomal gene, one copy from each parent.

Definition of Recessive and Dominant trait? Best Answer: Dominant trait refers to a genetic feature that hides the recessive trait in the phenotype of an individual. A dominant trait causes the phenotype that is seen in a heterozygous (Aa) genotype. Many traits are determined by pairs of complementary genes, each inherited from a single parent.est Answer: Dominant trait refers to a genetic feature that hides the recessive trait in the phenotype of an individual.

Recessive trait Recessive trait. Definition. noun. (genetics) A genetic trait that results from the expression of the two recessive alleles. Supplement. When the dominant allele is lacking or when the two alleles present are both recessive, their expression results in a recessive trait. Also called: 1  recessive character.

X-linked recessive inheritance X-linked recessive inheritance is a mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to be expressed in males and in females who are homozygous for the gene mutation, see zygosity. X-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. Carrier females who have only one copy of the mutation do not usually express the phenotype,

- Dominant and recessive traits. Using genetic principles, the information presented in a pedigree can be analyzed to determine whether a given physical trait is inherited or not and what the pattern of inheritance is. In simple terms, traits can be either dominant or recessive. A dominant trait is passed on to a son or daughter from only one parent.

Recessive Trait: Definition & Example Another way to define a recessive trait is one that is never expressed by the heterozygous genotype. For example, the heterozygous genotype for earlobe type (Ee) produces detached earlobes because the dominant allele (E) hides the effects of the recessive allele (e). recessive trait is the phenotype that is seen only when a homozygous recessive genotype for the trait of interest is present. This means that an individual must have two recessive alleles for the gene that determines this trait of interest.

Recessive trait If AA, Aa, and aa are distinguishable, each from the others, A and a are codominant. Recessive trait. An inherited trait that is outwardly obvious only when two copies of the gene for that trait are present—as opposed to a dominant trait where one copy of the gene for the dominant trait is sufficient to display the trait.

dominant allele recessive. allele, allelomorph - (genetics) either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character; some alleles are dominant over others.

What is the difference between dominant and recessive alleles for specific traits? Making the world better, one answer at a time. Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.

Definition of Recessive and Dominant trait? If they have one dominant allele and one recessive allele, they are referred to as heterozygous. A dominant trait when written in a genotype is always written before the recessive gene in a heterozygous pair. A heterozygous genotype is written Aa, not aA.f a genetic trait is recessive, a person needs to inherit two copies of the gene for the trait to be expressed. Thus, both parents have to be carriers of a recessive trait in order for a child to express that trait. If both parents are carriers, there is a 25% chance with each child to show the recessive trait.

Autosomal Recessive Definition. Autosomal recessive is one of several ways that a trait, disorder, or disease can be passed down through families. An autosomal recessive disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop.

Recessive (genetics) Of, or pertaining to, a gene (or allele) whose phenotypic expression is masked by a dominant gene (or allele). noun. (1) A recessive allele or trait. (2) An organism whose recessive trait is discernible or expressed.Supplement. In genetics, a recessive gene or allele is one in which the effect is not tangible, or is masked by the effects of the dominant gene.The recessive trait may be expressed when the recessive genes are in homozygous condition or when the dominant gene is not present.That happens when an organism inherits a pair of recessive genes from its parents. Word origin: Latin recess(us) , a withdrawal, receding part + - ive.he recessive trait may be expressed when the recessive genes are in homozygous condition or when the dominant gene is not present.

- (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).

We know many examples of traits controlled by recessive alleles; however, as scientists are more thoroughly studying the genetics of traits, they are finding that many have multiple genes and alleles associated with them, instead of just one gene with two alleles as explained above.

Dominant Trait: Definition & Example Dominant and recessive traits are heritable, meaning they can be passed on to offspring. Since there are two genotypes that show the dominant trait (homozygous dominant and heterozygous), it is sometimes possible for two individuals with dominant traits to have children with recessive traits.

Recessive Gene Recessive Gene. A recessive gene is a gene that is not dominant but only manifests when a gene of both parents is the same, i.e., homozygous (where both genes are the same as in two genes for blue eyes).hen there is both a dominant gene (brown eyes) and a recessive gene (blue eyes) in an allele (heterozygous), then the dominate gene manifests.

- 2.A dominant gene is one which is strong while a recessive gene is one which is weak. 3.A dominant gene will show up in the trait while a recessive gene, although still present, is masked or hidden by the dominant gene. 4.A recessive gene will only show up if the offspring inherits recessive genes from both parents.
