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

YES ALWAYS!!! Even if you have for example, Aa (A being the dominant allele and a being the recessive allele) that trait will always be dominant!

∙ 13y agoIn most cases it won't, however having the dominant and recessive can sometimes reduce the appearance of the dominant trait to a different degree.
Wiki User
∙ 12y agoIf you have a dominant allele, and a recessive allele, then the dominant allele will always be expressed (hence the term, dominant). You can do more research, but I think that this is right.

Is a recessive allele different from a dominant allele?
Yes, they are different. A recessive allele gets its name because when in the presence of a dominant allele, it will "recede" and not show, hence the name for the dominant allele.
What makes dominant alleles different from recessive alleles?
It's in the word! Dominant means bigger or stronger or greater. So the dominant allele is the stronger gene that is going to show whereas the recessive allele is still in you, but is overshadowed by the dominant allele.
What is a genotype with one dominant and one recessive gene?
The genotype of a person with one dominate allele for a gene and one recessive would be expressed as Aa or Yy. You can use any letter you would like except one will be shown as a capital (dominate) and one as a lower case (recessive). This combination is heterozygous for that trait.
Why a plant with yellow pods can never be a hybrid?
Yellow pods are a recessive trait and for this type of trait to show in the phenotype, both alleles have to be recessive. If there was a recessive allele (yellow) and a dominant allele(green) as it shows in hybrid pods, then the dominant allele would be the one shown and the pod would be green.
An allele that is hidden by other alleles is called?
i think the answer your lokking for is recessive Recessive is when you have a trait in your genome but it doesn't show in your physical appearance
Is a recessive allele different from a dominant allele?
Yes, they are different. A recessive allele gets its name because when in the presence of a dominant allele, it will "recede" and not show, hence the name for the dominant allele.
How Dominant allele different from recessive allele?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
What is the difference between the dominant and recessive allele for a trait?
An individual must have 2 recessive alleles in order for a trait to show up. One must only have 1 dominant allele in order for a trait to occur.
Recessive allele different from dominate allele?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
What is an allie that is covered up or hidden?
If you mean allele, then the answer is a recessive allele. A recessive allele is dominated by a dominant allele, and generally does not show up physically.
What makes dominant alleles different from recessive alleles?
It's in the word! Dominant means bigger or stronger or greater. So the dominant allele is the stronger gene that is going to show whereas the recessive allele is still in you, but is overshadowed by the dominant allele.

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 a genotype with one dominant and one recessive gene?
The genotype of a person with one dominate allele for a gene and one recessive would be expressed as Aa or Yy. You can use any letter you would like except one will be shown as a capital (dominate) and one as a lower case (recessive). This combination is heterozygous for that trait.
Are Recessive traits always shown in an organism's offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
Are recessive traits are always shown in an organism offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
Does a dominant allele mask a ressessive allele?
In diploid organisms (those with two copies of each gene carried on separate chromosomes), one of the copies of a given gene may differ from the other copy of the same gene on the twin chromosome. In some cases one version of the gene (the dominant allele) has the effect of 'masking' the activity of the other (the recessive allele); that is, the presence of the dominant allele negates the effect of the recessive allele on the organism's phenotype. There are many mechanisms which can cause this phenomena, and it depends on the particular genes involved, but a simple model is one where the recessive allele is a biochemically inactive version of the dominant allele. In this case the dominant allele would mask the effect of the recessive allele by providing an active version of the gene. The dominant phenotype would be the one which shows the downstream effects of this activity, and the recessive phenotype one which shows the downstream effects of a lack of activity. The dominant allele is said to 'mask' the recessive allele because only one copy is required to result in an elimination of the recessive phenotype, whereas all copies of the gene must be the recessive allele to result in the recessive phenotype.
