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:

What is X-linked Adrenoleukodystrophy causes by?
X-linked ALD is caused by defects in the ABCD1 gene, also known as the ALDP (ALD protein) gene
Which type of inheritance involves traits linked to a sex chromosome?
It is called sex-linked inheritance. If the sex-linked gene is on the X sex chromosome, it is often called X-linked inheritance.
Where is a human X-linked gene found?
A Y-linked gene is a gene that is carried on the Y chromosome, a sex chromosome found only in male cells. In humans, the most commonly mentioned Y-linked gene encodes a protein called testis-determining factor (TDF). As the name suggests, TDF prompts the development of the testes. Since only genetic males have a Y chromosome, only males express TDF and go on to develop testes. In general, genes carried on the sex chromosomes (X and Y) are considered to be "linked" to that chromosome. Genes carried on the X chromosome are considered X-linked in the same way that TDF is considered Y-linked.
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
Is the gene for blood clotting an X-linked gene?
YES
What is X-linked Adrenoleukodystrophy causes by?
X-linked ALD is caused by defects in the ABCD1 gene, also known as the ALDP (ALD protein) gene
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 Adrenoleukodystrophy on?
it is x linked an dpass down by the mother
What is a 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).
What is sex-linked gene?
It is a gene located on either sex chromosome (X or Y chromosome).
What is the opposite of independent assortment?
Linked gene inheritance. In humans, it is called x-linked inheritance; sex-linked inheritance is when the trait is carried on the X chromosome.
What are genes carried on the X chromosome?
A gene that is found on the X chromosome and not the Y chromosome is a sex-linked gene. That is why men tend to get only certain diseases. For instance, certain types of color blindness are recessive and carried only on the X chromosome. So if the mother carries the gene, then if the father donates another X, thus creating a daughter, then she will likely not have color blindness, since the father's X chromosome should balance it out if he doesn't have color blindness. However, a son with the affected gene from the mother would be certain to get it since that is the only gene he has concerning the red and green vision receptors.
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.
Which type of inheritance involves traits linked to a sex chromosome?
It is called sex-linked inheritance. If the sex-linked gene is on the X sex chromosome, it is often called X-linked inheritance.
