What is the result when a dominant allele pairs up with a recessive allele in simple dominance?
The dominant form of the trait shows. -Gradpoint
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.
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 does the word dominant mean in genetics?
In genetics, "dominant" refers to an allele that will be expressed in the phenotype if present, masking the expression of the corresponding recessive allele. This means that even if an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele's phenotype will be visible.
What is a trait expressed when two different genes for the same trait present?
If the two different genes include one dominant allele and one recessive allele, which is the heterozygous genotype, the dominant phenotype is expressed. For example, if R represents the red flower allele and r represents the white flower allele, the flowers would be red. If the trait is governed by incomplete dominance, then the heterozygous genotype (Rr) will produce an intermediate phenotype, such as pink.
Which is the dominant allele?
The dominant allele is the trait that shows up in the organism when the allele is present

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 does a dominant allele always do?
A dominant allele expresses its trait in an individual when present, masking the effect of a recessive allele. This means that if an individual has at least one copy of a dominant allele, the associated trait will be displayed.
Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?
a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).

What is the allele which is overuled?
The two types of alleles are dominant and recessive. The recessive allele will still be present but the recessive trait is not usually seen. However, is not always overruled. In the cases of codominance and incomplete dominance, the recessive trait still shows through some of the dominant one.
What is a dominant allale?
A dominant allele is a form of gene that masks the presence of a recessive allele when both are present in an individual. This means that the trait associated with the dominant allele will be expressed in the phenotype. Dominant alleles are typically represented by uppercase letters.
What does resscessive mean?
a resscessive allele, is hidden when the dominant trait is present
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.
