Is a gene located on an X or Y chromosome considered to be sex-linked?
Yes, a gene located on the X or Y chromosome is considered to be sex-linked.
Why does Lesch-Nyhan syndrome affect males?
Lesch-Nyhan syndrome is an X-linked recessive disorder, meaning the gene mutation responsible for the condition is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if they inherit the mutated gene on their X chromosome, they will develop the disorder. Females have two X chromosomes, so they are less likely to inherit the mutation on both X chromosomes.
What does it mean to say that a gene is linked to a chromosome?
When a gene is linked to a chromosome, it means that the gene is physically located on that chromosome. This means that the gene is inherited along with the chromosome it is located on, and may be inherited together with other nearby genes on the same chromosome.
What gene is affected by Barth syndrome?
Barth syndrome occurs when a person is born with a mutated, or abnormal, TAZ1 (or G4.5) gene. This abnormal gene is located on the X chromosome, which is a sex-determining chromosome. Males have one X and one Y chromosome, while females have two X chromosomes.
Explain why a woman carrying a gene for hemophlia can produce hemophilic sons when she is mated with a normal male?
A woman carrying a gene for hemophilia is typically a carrier with one X chromosome carrying the hemophilia gene and one X chromosome carrying the normal gene. When she is mated with a normal male who has one X chromosome and one Y chromosome, there is a 50% chance that the son will inherit the X chromosome carrying the hemophilia gene from the mother. Since males have only one X chromosome, if they inherit the hemophilia gene, they will express the disorder.
On which chromosome is the human gene known as Factor X located?
The Factor X gene is said to be located on the X chromosome. Females have two X chromosomes, whereas males only have one. The other chromosome they have is a Y chromosome.
What is a sex linked gene?
It is a gene located on either sex chromosome (X or Y chromosome).
What is sex-linked gene?
It is a gene located on either sex chromosome (X or Y chromosome).
What gene is sex-linked?
It is a gene located on either sex chromosome (X or Y chromosome).
Is a gene located on an X or Y chromosome considered to be sex-linked?
Yes, a gene located on the X or Y chromosome is considered to be sex-linked.
What is a sex-linked genes?
It is a gene located on either sex chromosome (X or Y chromosome).
Where is the gene for Btk?
The gene for Btk (Bruton's tyrosine kinase) is located on the X chromosome at position Xq21.32. Mutations in the Btk gene can lead to X-linked agammaglobulinemia, a primary immunodeficiency disorder.
What family of gene does coagulation factor VIII gene belong to?
It is located on the X sex chromosome.
A gene that is sex-linked is BEST described as what?
It is located on the X chromosome.

In all conditions where a defective gene is on the X chromosome transmission to a female can be through the mother or Father?
In cases where a defective gene is located on the X chromosome, a female can inherit the gene from either parent. If the mother carries one defective X chromosome, she can pass it on to her daughter. Similarly, if the father has the defective gene on his single X chromosome, he will pass it to all his daughters, as they inherit his X chromosome. Therefore, females can receive the defective gene from both maternal and paternal sources.
