Recessive traits require two recessive alleles.
There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
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.
A contributing allele is a genetic variant that is associated with a particular trait or disease. These alleles can have a small to moderate effect on the trait, increasing or decreasing the likelihood of developing that trait. Multiple contributing alleles can interact to determine the overall phenotype of an individual.
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
because it dominates the phenotype
He would have the recessive phenotype for that trait.
There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype
A recessive allele for a trait is expressed in the phenotype of an individual only when the individual is homozygous for that allele, meaning it has two copies of the recessive allele (one from each parent). If the individual has at least one dominant allele for that trait, the dominant trait will be expressed instead. Therefore, the presence of the recessive phenotype is only visible when both alleles are recessive.
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
Recessive allele is a trait that doesn't show in one's phenotype (observable trait) if there is a dominant allelle present. Only when you inherit a recessive allele from both parents (aa for example and not Aa) does the trait show in your phenotype.
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).
In order to express a recessive trait, an organism must have two copies of the recessive allele, one inherited from each parent. This is because the presence of a dominant allele will mask the effect of the recessive allele, preventing the recessive trait from being expressed. Thus, only when both alleles are recessive will the trait be visible in the organism's phenotype.
A capital letter in a phenotype typically stands for the dominant allele or trait. This means that if an organism has at least one copy of the dominant allele, the corresponding trait will be expressed.
