What kind of gene pair is found in the female carrier of a sex linked disorder?
In the female carrier of a sex-linked disorder, there would typically be one normal allele and one mutated allele for the gene associated with the disorder on the X chromosome. This is because females have two X chromosomes, and one copy of the X chromosome with the mutated allele can be masked by the normal allele on the other X chromosome.
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 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.
An individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
They are a carrier of the disease but do not show any symptoms because they have one normal allele that can compensate for the recessive disease-causing allele. If they have children with a partner who is also a carrier, there is a chance their offspring may inherit two copies of the disease-causing allele and develop the disease.
What feature of a pedigree would allow one to conclude that the disorder was caused by a dominant allele?
If the disorder is caused by a dominant allele, you would expect to see affected individuals in every generation of the pedigree, as it only takes one copy of the dominant allele to express the disorder. Additionally, affected individuals would have at least one affected parent.
What is true of sex linked alleles'?
A female with one copy of the allele will be a carrier, but not have the disorder.
What kind of gene pair is found in the female carrier of a sex linked disorder?
In the female carrier of a sex-linked disorder, there would typically be one normal allele and one mutated allele for the gene associated with the disorder on the X chromosome. This is because females have two X chromosomes, and one copy of the X chromosome with the mutated allele can be masked by the normal allele on the other X chromosome.
Is it true that a male with one copy of the allele will be a carrier of sex-linked alleles but not have the disorder?
No.
What is the genotype of a carrier of recessive disorder?
A carrier is someone who does not have a disorder but carries the allele on to offspring.
How is a carrier different from a person who has genetic disorder?
A carrier means that you have the gene for the disorder, but because the gene is recessive (meaning that it only shows when you have two recessive genes) and you obviously have a dominant gene as well, you won't show the disorder. Someone who actually has the disorder has two recessive genes. D = dominant gene r = recessive gene Dr = carrier, no signs rD = carrier, no signs DD = not a carrier, no signs rr = has the disorder
What is the genotype of a person who is a carrier of a autosomal recessive trait?

In biology an individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
carrier
Why are female carriers?
Females carry two X chromosomes; males only carry one. A female carrier carries a defective recessive allele for a gene on the X chromosome. Thus, the female will not be affected because she still has a copy of the dominant allele. However, if she has any male children, that child will be affected because males inherit their X chromosome from their mothers.
An individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
They are a carrier of the disease but do not show any symptoms because they have one normal allele that can compensate for the recessive disease-causing allele. If they have children with a partner who is also a carrier, there is a chance their offspring may inherit two copies of the disease-causing allele and develop the disease.
Why are x linked recessive traits more common in males than females?
Males have XY - therefore they only need one copy of the defective X in order to have the disorder.Females have XX - meaning they would need two copies of the defective allele in order to have the disorder. This means their father must have the disorder, and their mother must either have the disorder or be a carrier.
What is an organism that is heterozygous for a harmful trait?
An example of an organism that is heterozygous for a harmful trait is a carrier of a genetic disease like sickle cell anemia. In this case, the individual has one copy of the normal allele and one copy of the disease-causing allele, which can lead to the manifestation of the disease in offspring if they inherit two copies of the harmful allele.
What feature of a pedigree would allow one to conclude that the disorder was caused by a dominant allele?
If the disorder is caused by a dominant allele, you would expect to see affected individuals in every generation of the pedigree, as it only takes one copy of the dominant allele to express the disorder. Additionally, affected individuals would have at least one affected parent.
