There are two cases where this can happen:

Case 1: Codominance: Both alleles are equally present but are distinct. a good example of this is when you breed a white cow with a red cow. both white and red are dominant. when you look at the offspring, it is roan; it has both white and red hairs mixed in with each other.

Case 2: incomplete dominance: Both alleles are equally present but are not distinct. a good example of this is is when you mix a white flower and a red flower and you get a pink flower

When on e allele of a gene masks the presence of the other allele what form is masked?

The recessive allele.


What is an allele that produces a trait in the heterozygous condition called?

An allele that produces a trait in the heterozygous condition is called dominant. This means that only one copy of the allele is needed to express the trait.


What is it when an allele is neither dominant nor recessive?

When an allele is neither dominant nor recessive, it means that both alleles equally influence the trait. This is known as codominance, where both alleles are expressed in the phenotype of the individual.


When neither allele is dominant what are they expressed as?

Both of the alleles must be recessive. The trait expressed is a recessive trait.


What allele whose trait only shows up when no dominant allele is present?

Such a trait is called a recessive trait.


When neither allele is dominant (they are both expressed)?

Both of the alleles must be recessive. The trait expressed is a recessive trait.


An allele that is dominated or cover up by another allele is called what?

An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.


Why is a dominant allele called dominanat?

A dominant allele is called dominant because it expresses its trait even when only one copy is present in an individual's genotype. This means that if an individual has one dominant allele and one recessive allele for a particular gene, the dominant trait will be observed in the phenotype. This characteristic allows dominant alleles to mask the effects of recessive alleles, leading to the trait associated with the dominant allele being the one that is visibly expressed.


What is it called two forms of a trait are both dominant at the same time?

Codominance. It's the case of AB blood types, for instance. Neither trait is dominant over the other, so both manifest.


When a alleles creates a visible trait you call it what?

When an allele creates a visible trait, it is called a dominant allele. Dominant alleles mask the expression of recessive alleles when present in a heterozygous individual.


Why is a dominant allele called dominant apex?

because it dominates the phenotype


Which is the dominant allele?

The dominant allele is the trait that shows up in the organism when the allele is present
