Would you expect there to be more children with the dominant phenotype or recessive phenotypewhy?

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.


What does the word dominant mean in genetics?

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.


What is contributing allele?

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.


Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?

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.


Why do we call some alleles dominant?

because it dominates the phenotype

When one allele of a gene masks the presence of the allele what form can be seen in 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.


When allele of a gene masks the presence of the other allele what form can be seen in 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.


How does a dominant trait affect the phenotype of an organism?

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

What is a recessive allele?

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.


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 does a capital letter in phenotype stand for?

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.
