Why are recessive alleles not always expressed as the phenotype?

Recessive alleles are not always expressed as the phenotype because an individual needs to inherit two copies of the recessive allele (one from each parent) in order for it to be expressed. If an individual inherits just one copy of the recessive allele paired with a dominant allele, the dominant allele will determine the phenotype.


Which trait will be expressed if both dominant gene and recessive gene are in the gene pair?

The trait controlled by the dominant gene will be expressed, as it overrides the recessive gene in a heterozygous individual. The recessive gene will only be expressed if an individual inherits two copies of the recessive gene (homozygous recessive).


A gene is recessive when?

A gene is considered recessive when its effect is masked by a dominant gene in a heterozygous individual. This means that the trait associated with the recessive gene is only expressed when an individual inherits two copies of the recessive allele.


How do dominate traits over power the recessive?

Dominant traits are expressed over recessive traits because the dominant allele codes for a functional protein that masks the effects of the recessive allele. In a heterozygous individual carrying one dominant and one recessive allele, the dominant allele is expressed, leading to the dominant trait being observed.


How many copies of a recessive gene does it take to overpower a dominant gene?

It takes two copies of a recessive gene to overpower a dominant gene. This is because a dominant gene will be expressed over a recessive gene in individuals who carry one copy of each type.

Are alleles dominant or recessive?

Alleles are neither entirely recessive nor entirely dominate. An allele is any one of a number of alternative forms of the same gene on a chromosome.For example: say a flower only blooms either red or white flowers. There is a different allele for each color-- a red allele and a white allele. Now, one color may be dominate over the other recessive gene. For example, if the red color was dominate and the white color was recessive, then those certain alleles would be dominate and recessive, respectively. But alleles in general cannot be either recessive or dominate. It depends on the gene and it depends on the trait.


Why are traits controlled by recessive alleles on the X chromosome are more common in males than in females?

Males only have one X chromosome, so even if the gene on that chromosome is recessive there is no other gene that could dominate it. Females have two X chromosomes, so if the gene on that chromosome is recessive there is still a chance that the gene on the other chromosome could be dominate and override it.


What is a reccesive gene?

A recessive gene is a gene that is only expressed if an individual has two copies of it, one inherited from each parent. In the presence of another dominant gene, the recessive gene's trait is not expressed.


What is a genotype with one dominant and one recessive gene?

A genotype with one dominant and one recessive gene is called a heterozygous genotype. In this case, the dominant gene will determine the individual's trait or characteristic, as the dominant gene is always expressed over the recessive gene.


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.


Why are recessive alleles not always expressed as the phenotype?

Recessive alleles are not always expressed as the phenotype because an individual needs to inherit two copies of the recessive allele (one from each parent) in order for it to be expressed. If an individual inherits just one copy of the recessive allele paired with a dominant allele, the dominant allele will determine the phenotype.


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 is heterozygous dominate genotype?

It's actually just heterozygous. That means that one allele is dominant and one allele is recessive. The result is a dominant trait, but the recessive gene may come back in future generations.


Which trait will be expressed if both dominant gene and recessive gene are in the gene pair?

The trait controlled by the dominant gene will be expressed, as it overrides the recessive gene in a heterozygous individual. The recessive gene will only be expressed if an individual inherits two copies of the recessive gene (homozygous recessive).


Is mutation dominate or recessive?

it depends on what mutation you speak of. some are and some are not.


Genes that are only seen when paired with a recessive gene?

Recessive genes are only expressed when an individual has two copies of the recessive allele. If an individual inherits one dominant allele and one recessive allele for a particular gene, the dominant allele will be expressed phenotypically. The recessive allele will only be expressed if the individual inherits two copies of the recessive allele.


Which of these is a gene that does not express itself and is concealed by the presence of another gene of the same trait?

A recessive gene is a gene that does not express itself in the presence of a dominant gene of the same trait. When an individual inherits two recessive genes for a trait, the recessive gene will be expressed.
