∙ 15y agoA recessive allele. A dominant allele, when present, will be the only one physically expressed. For a recessive allele to be expressed, there must be two; one recessive allele from each parent.

∙ 13y agoIn a heterozygous allele pair, one dominant and one recessive allele for a trait are present in a person's genotype. Therefore it is the recessive allele that is not expressed.

What is a dominant alle?
The dominant allele is the one that determines the phenotype in a heterozygous individual.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
Do all heterozygous pairs of allele produce an intermediate phenotype?
No
What are the circumstances under which dominant alleles will be expressed?
A dominant allele will be expressed when an allele pair is homozygous or heterozygous dominant.
What is the genotype and phenotype of homozygous?
Are you talking about phenotype or genotype? Phenotype is the expression of the genotype. Genotype is what you inherited. Phenotype is what you see. Homozygous is the same. Heterozygous is different. If you inherit one allele for blue eyes and one allele for brown eyes, your phenotype should be brown eyes. Your genotype would be brown eyes, blue eyes. You would have a heterozygous genotype.
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 a alle?
The dominant allele is the one that determines the phenotype in a heterozygous individual.
What is a dominant alle?
The dominant allele is the one that determines the phenotype in a heterozygous individual.
What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
What happens when a ressive allele meetsup with a dominate allele?
The genotype is said to be heterozygous and the dominant trait will be expressed in the individual.
What is only way a recessive trait will be expressed?
if its 2 recessive allels together.
What is the phenotype of an individual with one allele for dimples and one for no dimples?
This would depend on whether the allele for dimples is dominant or recessive. If the allele for dimples is dominant and the no dimples allele is recessive then the phenotype of the individual would be dimpled. If the allele for no dimples is dominant and the allele for no dimples is recessive then the dimples will not be expressed. If these alleles are codominant then the dimples will be expressed but not as much as in an individual who has both alleles for dimples.
What is the phenotype of an individual with one allele for dimple and one allele for no dimples?
This would depend on whether the allele for dimples is dominant or recessive. If the allele for dimples is dominant and the no dimples allele is recessive then the phenotype of the individual would be dimpled. If the allele for no dimples is dominant and the allele for no dimples is recessive then the dimples will not be expressed. If these alleles are codominant then the dimples will be expressed but not as much as in an individual who has both alleles for dimples.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
What is the difference between a dominant and recessive allele?
Dominant is an allele that can be expressed in a heterozygous individual (ie. Bb) or homozygous dominant (ie. BB). Recessive on other hand are traits that will only be expressed in a homozygous recessive (ie. bb) condition. Under normal circumstances, dominant alleles are the ones expressed in the phenotype, while the recessive allele is not. For example (an extremely simplified example) an heterozygous individual for eye color. (genotype Bb), has one dominant allele, 'B', and one recessive allele, 'b'. Given that B is for brown eyes, and b is for blue eyes, that individual's phenotype would be expressed as brown eyes (and be recessive for blue eyes). Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
What is the phenotype of an individual with one alleles for dimples and one for one dimples?
This would depend on whether the allele for dimples is dominant or recessive. If the allele for dimples is dominant and the no dimples allele is recessive then the phenotype of the individual would be dimpled. If the allele for no dimples is dominant and the allele for no dimples is recessive then the dimples will not be expressed. If these alleles are codominant then the dimples will be expressed but not as much as in an individual who has both alleles for dimples.
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
