No, it is possible for 2 parents with Down syndrome to produce a child with no non-disjunction disorder because of a gamete is produced with an extra copy of the chromosomes.
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.
Nondisjunction results in cells with abnormal numbers of chromosomes due to chromosomes not separating properly in meiosis. this causes some cells to end up with to many chromosomes and others to end up with not enough chromosomes. It messes up cell division and development and can lead to death or genetic disorders like down syndrome.

There are two tendencies in nature: things tend to go to the lowest possible energy (enthalph) level (delta H = negative) and the highest possible state of disorder (entropy)
I think it would be unlikely that Asperger's Syndrome (AS) would be misidentified as high IQ; however, a person with Asperger's Syndrome might also have a high IQ. A person with AS will have various symptoms, some of which might cause a misdiagnosis of an attention deficit disorder (ADD or ADHD), obsessive-compulsive disorder (OCD), a learning disability, or other conditions. As an example, it seems unlikely that a medical professional would explain rarely speaking, an intense interest in doorknobs, lack of eye contact, or experiencing extreme anxiety when lights flash as having a high IQ. A person can have both Asperger's Syndrome and a high IQ, only Asperger's Syndrome, or only a high IQ. Some people with Asperger's Syndrome have a high IQ. Most people with a high IQ do not have Asperger's Syndrome.
The disorder is controlled by a recessive factor.
