What is the definition of a dominant trait in biology? When binary traits are available, they become classified as Dominant or recessive. A dominant trait is a trait the is evident by the appearance of the organism. A recessive trait is a trait the is present but is not evident in the appearance of the organism. Dark hair is a dominant trait to a recessive light hair trait. Two brunettes may have a chance of having a blonde child due to the fact that either of them may carry the blonde haired gene and not show it.

- You can open either with a text editor such as notepad, though a .bat file may have to be right clicked and then choose the Edit option rather than Open (Open means execute the code in the bat file). You can 'Save As' in a text editor such as notepad, in either format, by specifying the extension explicitly.

What is the function of stomata in plants? Best Answer: In botany, a stoma (also stomate; plural stomata) is a tiny opening or pore, found mostly on the under-surface (epidermis) of a plant leaf, and used for gas exchange.ecause their leaves are held vertically, they have the same number of stomata on the two epidermes. If the plant has floating leaves, there will be no stomata on the lower epidermis and they absorb gases directly from water through the cuticle. If it is a submerged leaf, no stomata will be present on either side.

- 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).

- 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.oun. (genetics) A genetic trait that results from the expression of the two recessive alleles. Supplement.

- 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.

Autosomal dominant Autosomal dominant or autosomal recessive. Refers to the inheritance pattern of a gene on a chromosome other than X or Y. Genes are inherited in pairs—one gene from each parent.However, the inheritance may not be equal, and one gene may overshadow the other in determining the final form of the encoded characteristic.utosomal dominant. adjective Referring to a trait or disorder that may be passed from one generation to the next when only one allele is required to pass a genetic defect to the progeny.

Is a unibrow a dominant trait?   Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will … be expressed only if both parents carry the trait.ou probably know of people who had unibrows while their parents didn't. If you have a heterozygous set of genes, meaning one of a kind, and unibrows are dominant, then it would mean you had one.

dominance Genetics The ability of a dominant gene to express itself in a phenotype, when the gene is paired with another (recessive) gene that would have expressed itself in a different way. Neurology The tendency of one brain hemisphere to be more controlling than the other in mediating neural activity.

Genetics Dominant. DEFINITION: descriptive of an allele in a heterozygous individual that appears to be the only one affecting a trait EXAMPLE: the brown-eyed gene SENTENCE: The baby had the blue-eyed gene along with the brown-eyed gene, but the baby had brown eyes because of it's dominance.

What is the definition of a dominant trait in biology? Answer Wiki. In terms of alleles, we have two alleles for each phenotype (assuming Mendelian genetics, which is most common for dominant/recessive assessment). To really simplify things, some traits are decided depending on the alleles present, search the pea experiment for example.

- Autosomal dominance is a pattern of inheritance characteristic of some genetic diseases. Autosomal means that the gene in question is located on one of the numbered, or non-sex, chromosomes. Dominant means that a single copy of the disease-associated mutation is enough to cause the disease.

What does it mean to have a dominant trait? A recessive trait is a trait that most people don't have. If a parent of a child has red hair, it is recessive but there is a greater chance because of the gene in the redheaded parent's genetic-system, may be biologically transferred to the offspring.

Recessive Trait: Definition & Example Normally, individuals have two alleles for one gene. A dominant allele is usually designated by an uppercase letter and masks the effects of another allele, the recessive allele. Recessive alleles are normally represented by lowercase letters and is - as you can no doubt guess - the non-dominant allele.

- 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.t is a relationship between alleles; one allele can be dominant over a second allele, recessive to a third allele, and codominant to a fourth. Also, an allele may be dominant for a particular aspect of phenotype but not for other aspects influenced by the same gene.

What is a Dominant Trait? When someone is heterozygous for a trait, the difference between dominant and recessive traits becomes more important, because the dominant trait is the one which will manifest. In 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.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.
