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.
Multiple 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
EXAMPLE: DNA
An 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.
Alleles 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.
ABO blood group, a is dominant to o and b too
The dominant allele for brown eyes (B) over the recessive allele for blue eyes (b).
Blood types like A,B or o

The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
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.
The frequency for the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.
An allele that is always expressed when it is present is the dominant allele.
multiple allele inheritance.
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.
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.

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".
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.
blood type is an examples of multiple-allele inheritance.
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!
