an allele is an alternative form of a gene that governs a characteristic, like hair or eye color. an individual gets 1 allele for each charecteristic from each parent. There are dominant alleles and recessive alleles. The dominant allele is the allele that is the person's physical appearance, and the recessive allele is the one that isn't visible but the person has in his/her genotype.

∙ 13y agoMultiple alleles means that for a specific locus on a chromosome there can be 3 or more forms of that gene (allele). Only one allele can be inherited because they are found on homologous chromosomes. Height is not a multiple allele because it is associated with many genes on several chromosomes (plus environmental factors) so this would be polygenic inheritance.
Multiple allele trait is the ABO group. The allele for A B or O (3 alleles ) is found on the same locus, therefore only one of them could be inherited

∙ 10y agoAn allele is a form of a gene. you get 2 alleles for a trait, one from each parent.
A dominant allele is is the allele that is shown in a person's phenotype. A recessive allele is not visible, but is in a person's genotype. Both dominant and recessive alleles can be passed to the individual's offspring.

∙ 11y agoAlleles are a particular form of a specific gene. There are often many possible alleles that can be inherited for one gene. One example is in the blood types. There are three possible blood type alleles that one can possess; IA, IB and IO which code for blood type A, B and O respectively.

What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
How do you write alleles?
It will be the lowercase form of the dominant allele. For example the dominant form for tallness is T, the recessive allele for shortness is t.
What is an example of allele frequency?
The frequency for the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.
Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
ABO blood group expression is an example of?
multiple allele inheritance.
What is am example of a dominant allele?
A dominant allele is the allele which expresses itself morphologically.for example;the dimple on your cheek.your mom has a dimple whereas your father doesn't have it .but you too possess it.then ,your mother's allele serves to be the dominant allele.
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.

Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
What is the general term for an allele that masked in the phenotype by the present of another allele?
Recessive. It is denoted by the lower case version of the first letter of the Dominant gene. For example, if the dominant is "A" then the allele is "a".
Is an allele bigger then a gene?
An allele is a gene. It is one form of a gene. For example, height in pea plants is controlled by one gene with two forms. A pea plant can be tall or short. There is a short allele and a tall allele for the gene governing height.

multiple allele inheritance.
What is an example of multiple alleles?
blood type is an examples of multiple-allele inheritance.
If and individual has one dominant allele and one recessive allele will the recessive allele show up?
YES ALWAYS!!! Even if you have for example, Aa (A being the dominant allele and a being the recessive allele) that trait will always be dominant!
