Is it true that a female with one copy of the allele will be a carrier and have the disorder?
It depends on the type of disorder being discussed. For X-linked recessive disorders, a female with one copy of the mutated allele (being heterozygous) will typically be a carrier but not exhibit symptoms of the disorder. However, for autosomal dominant disorders, having one copy of the allele is sufficient for the individual to express the disorder. Therefore, the specifics of the allele and disorder in question are crucial for an accurate answer.

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 genotype for a recessive trait found on the female chromosome?
The genotype for a recessive trait found on the female chromosome typically consists of two copies of the recessive allele (homozygous recessive, e.g., "aa") or one copy of the recessive allele and one copy of the dominant allele (heterozygous, e.g., "Aa"). In females (XX), if the trait is located on one of the X chromosomes, a female must have two copies of the recessive allele on both X chromosomes to express the recessive trait. If she has one dominant allele, she will be a carrier but not express 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 genotype is used to describe a carrier?
A carrier for a recessive genetic trait is typically described with a heterozygous genotype, represented as "Aa." In this case, "A" denotes the dominant allele, while "a" represents the recessive allele. The carrier possesses one copy of the recessive allele but does not express the trait associated with it, as the dominant allele masks its effects.

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

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.
In biology an individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
carrier
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.
