- (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.

- According to the Morton Salt website, mixing up a paste of salt and lime or lemon juice will clean the rust from bicycle handlebars and rims. Morton advises you to mix six tablespoons of salt with two tablespoons of juice in order to make a paste. Then, rub that paste on to the rusty parts of the bike.

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.

Contents: Dominant vs Recessive Genes determine traits, or characteristics, such as eye, skin, or hair color, of all sexually-reproducing species. Each gene consists of two alleles: one comes from the mother and one from the father. Some alleles are dominant, meaning they ultimately determine the expression of a trait.Other alleles are recessive and are much less likely to be expressed.When a dominant allele is paired with a recessive allele, the dominant allele determines the characteristic. When these traits or characteristics are visibly expressed, they are known as phenotypes.The genetic code behind a trait is known as the genotype.hen a dominant allele is paired with a recessive allele, the dominant allele determines the characteristic. When these traits or characteristics are visibly expressed, they are known as phenotypes.

Ideal Pedaling Speed for Bicycles Seventy to 100 revolutions per minute is an ideal cadence for most cyclists. Riding a bike over short distances is simple and relaxing, but when you start putting many miles under your wheels or climbing steep hills it can be a tough workout. Maintaining an ideal pedaling speed helps to counteract the rigors of a long ride on your body. Cyclists refer to their pedaling speed as cadence.

- 1 Dominant: a trait that is visible and can cover up other traits when there is more than one present. 2  Genotype: the genetic makeup of an organism, or the versions of a gene that an organism has. 3  Heterozygous: having two different versions of a gene. 4  Homozygous: having two identical versions of a gene.

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.

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.

- 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.

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.

Definition of Recessive and Dominant trait? For example, if a person has one gene for blue eyes and one for brown, that person will always have brown eyes because they are the dominant trait. For a person to have blue eyes, both their genes must be blue (recessive). When a person has two dominant alleles, they are referred to as homozygous dominant.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.est 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.

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.lso, an allele may be dominant for a particular aspect of phenotype but not for other aspects influenced by the same gene. Dominance differs from epistasis, a relationship in which an allele of one gene affects the expression of another allele at a different gene.

What is a dominant trait? A dominant trait is the trait that will show. A recessive trait is the trait that is hidden. For example if your mom had brown eyes and your dad has green eyes you would have … brown eyes because brown eyes are the dominant trait. 3 people found this useful.

What is the difference between dominant traits and recessive traits? A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent. An individual with one dominant and one recessive allele for a gene will have the dominant phenotype.

What is homozygous dominant? Homozygous dominant-means having dominant alleles at the same locus on a chromosome.More correctly, it's the same locus on two chromosomes (a homologous pair).or simple homozygous dominant, it would be AA. (Note: The letters 'AA' are not neccessarily what it would be. It depends on the trait, if it's the color green let's say, it w … ould be probably GG. It doesn't really matter what letters, just as long as they are uppercased and the same.

- Definitions. A dominant trait is one that is expressed in an individual who has only one copy of that gene. A recessive trait occurs when a person gets two copies of a mutant gene, or one from each parent.ow They Are Expressed. Dominant and recessive traits are expressed differently when referring to the Punnett Square developed by Gregor Mendel. A dominant trait is expressed by an uppercase letter, while a recessive gene is represented by a lower case letter.

"What does the term ""recessive"" mean in biology?" Red hair can be looked at as recessive, which means that both copies of your gene for hair color have to be red in order for you to have red hair. Brown hair is dominant, which means that if you have one copy of red and one copy of brown, then you will have brown hair, because it's expression is stronger(dominant). Hope this clears things up for you.
