Prader-Willi Syndrome is neither dominant or recessive - it is simply a genetic anomaly that occurs at conception (it's not inherited - it just happens) where part of the 15th chromosome that should be present/active is missing. This occurs either because it is totally missing (known as deletion) or because the child gets 2 chromosome 15s from the mother (instead of 1 from mom and 1 from dad which is the way it should be) and therefore that part of chromosome 15 that should be active from the father is nonexistent (this is known as uniparental disomy, or UPD)

What kind of mutation is triple x syndrome?
Most cases of triple X syndrome are not inherited so it is not a dominant or recessive trait.
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
Is the Huntingtons gene inherited as a dominant or ressisive gene?
It is inherited by a dominant gene.
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
If you have Andersen's syndrome what are the chances that your two children will have it?
Andersen's syndrome is usually inherited in an autosomal dominant fashion. This means that EACH child of a person with Andersen's syndrome will have a 50% chance of inheriting the gene associated with the syndrome. However, not all people who inherit the gene will show symptoms of the syndrome. Children of people affected with Andersen's syndrome should be evaluated by a qualified physician to determine risk.
Is marfan syndrome automsomal dominant?
Yes, Marfan syndrome is autosomal dominant.
Autosomal dominant genetic disorder?
An autosomal genetic disorder is Huntington's disease.
If only one parent has to have the gene for Marfan Syndrome to pass it on it is dominant or recessive?
Japanese I'm pretty sure that wasnt one of the options
What is a homozygus?
