X linked diseases when recessive are only present in female children when both parents have the disease. If the mother is only a carrier of the disease then each male child would have a 50% probability of having the disease, but no female children would be affected (50% would be carriers).
Hemophilia is an example of a recessive X linked genetic defect:

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 is an X linked traits?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
What causes X-linked agammaglobulinemia?
It is caused by a defect in the gene that codes for Btk
If a daughter expresses an x-linked recessive gene she inherited the trait from?
If a daughter expresses an X-linked recessive gene, she inherited the trait from her father who carries the gene on his X chromosome. Since males only have one X chromosome, if they have the gene, daughters will always inherit it from their father.
Is a sex-linked gene found on one sex chromosome but not on the other?
Yes, a sex-linked gene is located on one of the sex chromosomes (X or Y), but not both. This means that the inheritance of the gene is dependent on the individual's sex. For example, genes on the X chromosome are considered sex-linked because males have only one X chromosome, while females have two.
Is the gene for blood clotting an X-linked gene?
YES
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.
How do you use the words sex-linked gene in a sentence?
Sex-linked genes, genes found on one of the sex chromosomes (X or Y) but not the other. Most sex-linked genes are X-linked because the female chromosome is longer.
What does X-linked mean as it relates to chromosomes?
X-linked refers to a gene carried on the X chromosome, one of the two sex chromosomes.

What gene is sex-linked?
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).
A trait controlled by a gene on the sex chromosome is know as a?
A trait controlled by a gene on the sex chromosome is known as a sex-linked trait. These traits are often inherited in a sex-specific manner, with different patterns of inheritance depending on whether the gene is located on the X or Y chromosome.
What is the defineion to sex linked trait?
A sex linked trait is from a gene that is on either the x or y chromosomes
A gene that is sex-linked is BEST described as what?
It is located on the X chromosome.
A trait which is inherited on sex chromosomes is?
Color blindness is an example of a trait that is inherited on sex chromosomes. It is passed down on the X chromosome, and males are more likely to be colorblind because they have only one X chromosome.
