What else can I help you with?
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 recessive and dominant mean?
I am pretty sure the recessive and dominant alleles you are talking about are covered in Biology. Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).
What are two forms that a gene or allele may take?
A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
What are the difference between dominant and recessive genes?
Dominant genes will cover up recessive genes. Take a simplified version of eye color for example. Brown is dominant and blue is recessive. Someone might have the allele for both brown and blue, but their eyes will be brown because of the dominent brown gene. If there are two parents that carry the recessive gene, neither will be blue eyed, but they will have a chance of having a blue eyed child if both pass on the recessive gene.
When a trait is not expressed when paired with a dominant allele is the definiton of?
The trait that is not expressed when paired with a dominant allele is known as a recessive trait. It is masked by the dominant trait in individuals carrying both alleles.
Which genes are dominant and which are recessive?
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
Which form of a gene pair is expressed when both dominant and recessive are present?
apples
How is Dominant and Recessive differ?
Dominant traits are expressed when just one copy of the gene is present, while recessive traits require two copies to be expressed. Dominant traits mask recessive traits when they are both present.
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
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 recessive and dominant mean?

Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).
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 is a trait that needs two factors in order to be expressed?
Actually, it is the recessive.................................................................UR WELCOME! :)
What are two forms that a gene or allele may take?
A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
Comapre and contrast dominant and recessive traits?
Dominant traits are characterized by a single copy of a gene being sufficient to express a certain trait, whereas recessive traits require two copies of the gene (one from each parent) for the trait to be observed. Dominant traits typically mask the expression of recessive traits when both are present.
What are the difference between dominant and recessive genes?
Dominant genes will cover up recessive genes. Take a simplified version of eye color for example. Brown is dominant and blue is recessive. Someone might have the allele for both brown and blue, but their eyes will be brown because of the dominent brown gene. If there are two parents that carry the recessive gene, neither will be blue eyed, but they will have a chance of having a blue eyed child if both pass on the recessive gene.
What is a gene which is stronger and therefore expressed or shown in the phenotype?
I think the answer your looking for is "the dominant". However depending on what the gene codas for occasionally if both a dominant and recessive are present a different expression will be observed compared to just dominant or just recessive.
