Since Down syndrome isn't a sex-linked trait, it won't be passed down from parent to child, and it has nothing to do with the genetics of the previous generations. Getting Down syndrome happens by a "mess up" in reproduction, not from getting it from previous generations.

What is the focus of the research being done on Down syndrome?
From the Down Syndrome Research Center of Stanford University:It is known for causes the disorder. It's the increased activity of the extra genes on chromosome 21. Unlike other disorders, where genes are mutated or missing, in Down syndrome there are just too many copies of particular genes. The task of identifying the genes that cause Down syndrome, and trying to shut off the activity of the extra genes, is in theory much simpler than trying to fix a mutated gene or trying to add one that is missing.See the Related Link to the Down Syndrome Research Center of Stanford University.
Are women responsible for the Down syndrome disease?
No
Is it true to state that female only are responsible for down syndrome?
no and waverer some kids have down syndrome
How is Zellweger syndrome caused?
Zellweger syndrome is caused by mutations in genes that are involved in the formation of peroxisomes, which are cell structures responsible for breaking down fatty acids. These mutations lead to the absence or dysfunction of peroxisomes in cells, resulting in the accumulation of toxic substances and causing the characteristic symptoms of the syndrome.
Is Down Syndrome the same as Marfan Syndrome?
No. Down is caused by an extra chromosome while Marfan is due to a mutation in one or more genes.
What is the most common cause for down syndrome?
Down's syndrome is a disorder caused by defective genes. It is most commonly caused by parents who are elderly at the time of birth.
Is it possible for 2 parents with down syndrome to produce a child with no non-disjunction disorder please explain why?
Since Down Syndrome is not genetic and is a trisomy, dominant and recessive genes do not play a role and it is possible for two down syndrome parents to have a child without down syndrome.
What genes are responsible for neuronal migration disorders?
The most well characterized genes include DCX on the X chromosome, responsible for double cortex syndrome, and LIS1 on chromosome 17, the first gene identified for lissencephaly.
Is Down syndrome caused by single or multiple genes?
it's the duplication of the 21st chromasome
Why is Down syndrome physical?
Down syndrome is a genetic condition that not only affects the brain but also affects physical appearance because of the genes affected by the disease. Sorry I don't know how exactly the genes are distorted. But they affect physical appearence.
Do people with Down Syndrome have 47 genes?
People with Down syndrome typically have 47 chromosomes, not genes. This extra chromosome is usually a third copy of chromosome 21, leading to the condition often being referred to as trisomy 21. The presence of this extra chromosome affects various physical and intellectual traits associated with Down syndrome.
Does Hannah Gosselin have down syndrome?
No she does not. The prominence in the foreheads of most of the children is caused by the inherited Asian genes from the father.
