What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?

What does a dominant allele does this to another allele?

A dominant allele will mask the expression of a recessive allele when they are present together in an organism. The dominant allele will be expressed, while the recessive allele will not be visibly expressed in the organism's phenotype.


What the 2 alleles are that control a specific characteristic?

The two alleles that control a specific characteristic are typically referred to as the dominant allele and the recessive allele. The dominant allele is expressed in the phenotype when present with a recessive allele, while the recessive allele is only expressed when two copies are present.


What are the circumstances under which dominant alleles will be expressed?

Dominant alleles are expressed when an individual has at least one copy of the dominant allele in their genotype. This means that even if there is a recessive allele present, the dominant allele will be the one observed in the phenotype. Dominant alleles mask the expression of recessive alleles when they are both present in an individual's genetic makeup.


Does a recessive allele need another recessive allele to be expressed?

Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.

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.


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.


True or False In heterozygous individuals only the recessive allele is expressed?

In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed

What is dominant recessive?

There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).


What does a dominant allele does this to another allele?

A dominant allele will mask the expression of a recessive allele when they are present together in an organism. The dominant allele will be expressed, while the recessive allele will not be visibly expressed in the organism's phenotype.


When is a recessive allel expressed in offspring?

A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.


What the 2 alleles are that control a specific characteristic?

The two alleles that control a specific characteristic are typically referred to as the dominant allele and the recessive allele. The dominant allele is expressed in the phenotype when present with a recessive allele, while the recessive allele is only expressed when two copies are present.


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.


Not expressed when the dominant form of a trait is present?

Recessive traits are not expressed when the dominant form is present. This is because the dominant allele masks the expression of the recessive allele in the heterozygous condition. Only when an individual has two copies of the recessive allele will the recessive trait be expressed.


What are the circumstances under which dominant alleles will be expressed?

Dominant alleles are expressed when an individual has at least one copy of the dominant allele in their genotype. This means that even if there is a recessive allele present, the dominant allele will be the one observed in the phenotype. Dominant alleles mask the expression of recessive alleles when they are both present in an individual's genetic makeup.


What happens to the recessive allele in a heterozygous offspring?

In a heterozygous offspring, the recessive allele is present but not expressed because the dominant allele masks its effects.
