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

∙ 11y agoWhen neither of the alleles for a trait are dominant that makes the trait recesive.

∙ 13y agowhen two alleles for one trait are present and neither allele overshadows the other is demonstrated
wrong actually it is incomplete dominant *la vakita was here*:)

An allele that is dominated or cover up by another allele is called what?
It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
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.
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
What gene is defined as a gene that controls the appearance of a certain trait?
the dominant allele

When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
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.
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be 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.
What is a person who has one recessive allele for a trait and one dominant allele for the same trait and is able to pass in the trait on to their offspring?
That is heterozygous. Some scientist call these "hybrids"(no joke)The person is heterozygous for that trait and will have the dominant phenotype.An organism with both a dominant and recessive allele for a specific trait is called an heterozygote. They are heterozygous for this trait.
Which is the dominant allele?
The dominant allele is the trait that shows up in the organism when the allele is present

What gene won't display its trait in the prescience of a dominate trait?
The recessive form of a gene, called a recessive allele, will not be expressed in the presence of the dominant form of the gene, called a dominant allele.
What gene is defined as a gene that controls the appearance of a certain trait?
the dominant allele
