What else can I help you with?
If the allele for having a white forelock is dominant family members WITHOUT a white forelock are?
Family members without a white forelock must possess two recessive alleles for that trait, as the white forelock is dominant. This means they can only pass on the recessive allele to their offspring, ensuring that none of their children will have a white forelock unless the other parent contributes a dominant allele. In genetic terms, these family members are homozygous recessive for the trait.
What is the genotype of a person who is a carrier of a autosomal recessive trait?
The genotype of a person who is a carrier of an autosomal recessive trait is typically heterozygous, meaning they carry one copy of the recessive allele and one copy of the dominant allele for that trait. This would be represented as Aa, with the lowercase "a" representing the recessive allele.
What carrier of a trait controlled by a allele does not express the trait?
A carrier of a trait controlled by a recessive allele possesses one copy of the recessive allele and one copy of the dominant allele. This means that they do not express the trait associated with the recessive allele because the dominant allele masks its effect. However, the carrier can pass the recessive allele to their offspring, who may express the trait if they inherit two copies of the recessive allele.
What is member of a gene pair that determines a specific trait is?
an allele
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.

Family members without a white forelock must possess two recessive alleles for that trait, as the white forelock is dominant.

In genetic terms, these family members are homozygous recessive for the trait.
If the male parent is heterozygous for a trait what alleles for each sperm cell possibly have?
A heterozygous male parent has two different alleles for a trait. During gamete formation, each sperm cell will carry one of the two alleles, either the dominant or recessive allele. This means that half of the sperm cells will carry one allele and the other half will carry the other allele.
What is the genotype of a person who is a carrier of a autosomal recessive trait?
The genotype of a person who is a carrier of an autosomal recessive trait is typically heterozygous, meaning they carry one copy of the recessive allele and one copy of the dominant allele for that trait. This would be represented as Aa, with the lowercase "a" representing the recessive allele.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
What carrier of a trait controlled by a allele does not express the trait?
A carrier of a trait controlled by a recessive allele possesses one copy of the recessive allele and one copy of the dominant allele. This means that they do not express the trait associated with the recessive allele because the dominant allele masks its effect. However, the carrier can pass the recessive allele to their offspring, who may express the trait if they inherit two copies of the recessive allele.
In a heterozygote the allele that does not affect the trait?
The allele that does not affect the trait in a heterozygote is known as the recessive allele. This allele is masked by the dominant allele, which determines the observable trait. However, the recessive allele can still be passed on to offspring if both parents are carriers.
What is member of a gene pair that determines a specific trait is?
an allele
What is the difference between dominant and recessive alleles for specific traits?
Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
Why can a person with brown eyes carry blue eye alleles but a person with blue eyes cannot have a brown eye allele in their genotype?
A person with brown eyes can carry the blue eye allele because brown is a dominant trait, so they can have both blue and brown alleles in their genotype. However, a person with blue eyes cannot have a brown eye allele because blue eyes are a recessive trait, meaning they must have two copies of the blue allele in their genotype to express the trait.
The appearance of a recessive trait in offspring of animals most probably indicates that?
both parents carry a copy of the recessive allele for that trait. This means that the offspring inherits two copies of the recessive allele, expressing the trait. If both parents were carriers of the recessive allele, there is a 25% chance of the offspring inheriting two copies and showing the trait.
