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.

What is allele masked by the dominant allele?

An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).


In one allele is dominant to a recessive allele?

In a dominant-recessive allele relationship, the dominant allele will be expressed phenotypically over the recessive allele. This means that even if an organism carries one dominant and one recessive allele for a particular trait, the dominant allele will determine the observable characteristic.


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.


Which form of gene pair is expressed when both dominant and recessive are present?

In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.


Is albinism controlled by a dominant allele or by a recessive allele?

Recessive allele.


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.


Does recessive allele is expressed if there is no dominant allele present?

Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype. This is because in the absence of a dominant allele, the recessive allele has the opportunity to be expressed in the phenotype.


If and individual has one dominant allele and one recessive allele will the recessive allele show up?

No, the dominant allele will be expressed in the individual's phenotype, masking the presence of the recessive allele. The recessive allele will only be expressed if an individual inherits two copies of the 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.


Allele that prevents the expression of a recessive allele?

A dominant allele


Is a recessive allele different from a dominant allele?

Yes, a recessive allele is masked or overridden by a dominant allele in a heterozygous individual. This means that the dominant allele's trait will be expressed. In contrast, a recessive allele's trait will only be expressed if an individual has two copies of the recessive allele.


What type of allele is masked when a dominant allele is present?

The recessive allele is masked when a dominant allele is present. Dominant alleles are expressed over recessive alleles in heterozygous individuals.
