That isn't physically possible. All XO individuals are females with Turner's syndrome. Individuals with only a Y chromosome do not survive.

Is huntingtons a chromosomal or a genetic disease?
Hungtington's disease is a dominant mutation in the gene that codes for the protein 'Huntington' It only affects a single gene, the remainder of the chromosome is unaffected and therefore it is not a chromosomal abnormality
Why does a female with a gene for a sex-linked disorder usually appear normal?
A female with a gene for a genetic disorder will usually only have it on one of her two X chromosomes. The other chromosome will carry the healthy version of the gene, which will carry out that gene's function when the other chromosome cannot. Males will exhibit the disease if they have the gene as a male human only has one X chromosome. So, in order for a female to have a genetic disorder carried on her sex chromosome her mother would have to have the defective gene and her father would have the disorder.
How is Jacobs syndrome inherited?
It's not. Jacob, XYY, syndrome is completely random disease; unlike most genetic diseases. It is caused by the accidental inheritance of an extra Y chromosome. Typically a father only gives one Y chromosome, but one mistake can cause a sperm to to carry that extra chromosome.
How do you know if you have got huntingtons disease?
First, since this is a genetic disease, that is transmitted only by inheritance, a determination of family history of HD is usually made. There are also characteristic symptoms that become noticeable in later life, most commonly chorea- or uncontrolled movements of the body. In recent years, a genetic test has been developed that permits screening the the chromosome that causes HD- if you do not have that chromosome, you do not have, and will not develop HD. If you DO have that chromosome, at some point the symptoms of HD will develop. The exact age varies from one person to another. There is additional information at the website of the Huntington's Disease Society of America.

A bacterium has one that holds its genetic material?
yes. it has only one chromosome that holds its genetic material, however they may also have plasmids that contain genetic material
What is the only way you can get a genetic disease or sickness?
The only way one can get a genetic disease is by inheriting it through one's parents. Genetic diseases and sicknesses aren't contagious, except through birth.
Is it true that women have some protection from genetic disease because they carry only x chromosomes?
Yes- but only in the case of a genetic disease that is carried ONLY on the Y chromasome.
What is huntington's disease classified as?
It is a genetic disease. You can only "catch" it by inheriting the gene for it.
What chromosome is affected in fabry disease?
The allele that is responsible of Fabry Disorder/Disease is located on the X chromosome and is the only lipid storage disorder identified as being sex linked.
Can a raccoon have Down's syndrome?
No, Down's syndrome is only a human genetic disorder. Those with the disorder have an extra chromosome. Raccoons do not get this particular genetic disorder.
What kind of defect is CGD?
recessive defect meaning that both copies of the chromosome must have the defect before it can be expressed. Females who have one X chromosome without the defect do not get this disease. Males, since they only have one X chromosome, get the disease
