An individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
Is a carrier of that disease. Aa a being the recessive gene
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
Why are sex-linked traits most commonly displayed in males?
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.
How do you know that a pea plant with wrinkled seeds does not have one copy of the round seed allele?
The trait associated with the allele is not expressed in heterozygotes.
Are males most likely to have an x-linked disorders?
Males are much more likely to be affected by an x-linked disorder because they only have one copy of the x-allele, so if they carry an abnormal version, it will be expressed. On the other hand, since women have two copies of the x-allele, they would need two copies of the abnormal gene to show the disease.
What is true of sex linked alleles'?
A female with one copy of the allele will be a carrier, but not have the disorder.
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.
In Which statements is true of linked alleles?
With one copy will be a carrier but not have a the disorder
In biology an individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
carrier
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.
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.
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.
An individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?

How are genes located on the same chromosomes inhereted?
They are inherited based on which copy of an allele is in the reproductive cells of the male and female at fertilization.
How is it possible for someone to carry a disorder but not actually have it?
This most commonly occurs if the disorder is recessive, meaning you must carry two copies of the gene which causes the disorder in order to show it.Everyone has two copies of each gene, one paternal and one maternal. If you only carry one copy (allele) of the gene which causes the recessive disorder and your other copy of that gene is normal, you will not have the disorder. However, you can carry it on if you have a child with someone else who also carries the gene which causes the disorder and the child gets two copies of the disorder gene.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
What are two forms that a gene or allele may take?
A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
