A dominant allele is an allele where its phenotype will always be represented when the allele for that gene is present. A recessive allele can be masked by a dominant allele when a dominant and recessive allele are present for the same gene. A recessive allele will only present itself when two recessive alleles for a trait are present.

Dominant alleles are traits that show on the physical form of the organism.
Recessive alleles are traits still there in the organism, but they will not show unless there is no dominant alleles.

∙ 9y agoA dominant allele is one which expresses what it codes for such as eye color no matter what the other allele is. A recessive allele will only express what it codes for if there is a recessive pair. All alleles come in pairs except on the XY chromosomes. For eye color Brown is dominant and blue is recessive so...
(B=brown b=blue)
BB = brown eyes
Bb = still brown eyes even though there is one blue allele
bb = this is the only combination where you can get blue eyes
Or
simple dominance for gradpoint!

∙ 12y agoAn allele that can express itself (produce its phenotype) even in the presence of the other allele is said to be dominant to the other allele.
The allele that cannot express itself when its dominant allele is present is called the recessive allele.
For example, gene T governs height in pea plants. The "T" allele produced tall plants, while the "t" allele produces dwarf plants. Plants having genotypes TT and tt would no doubt be tall and dwarf respectively. However, plants with genotype Tt (heterozygous) will not be intermediate height, they will be tall. Here, the effect of the T allele is dominating the effect of the t allele. Hence T is dominant and t is recessive

A recessive allele could be freckles, a widows peak, clef chin, or left handedness.

Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
An allele that is able to cover the recessive?
dominant allele will overthrow a recessive one
What gene is masked if it is paired with a dominant gene?
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
Allele that is fully expressed is referred to as?
No, it is referred to as dominant
What is the difference between dominant and recessive alleles for specific traits?
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.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
What is it Dominant allele What is a recessive allele?
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
What allele is covered up by the dominant allele?
An allele that's masked by a dominant gene is called a "Recessive"recessiverecessive traitThe recessive allele. Often depicted as the "small r" in examples: Rr, R=dominant, r= recessive.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
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!
What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
In one allele is dominant to a recessive allele?
In _____, one allele is dominant to a recessive allele.
Is a recessive allele different from a dominant allele?
Yes, they are different. A recessive allele gets its name because when in the presence of a dominant allele, it will "recede" and not show, hence the name for the dominant allele.
How Dominant allele different from recessive allele?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
Is albinism controlled by a dominant allele o recessive allele?
It is controlled by a recessive allele.
