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.
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.
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.
Functional disorder
Choose a chromosomal disorder from the March of Dimes Foundation Web site. Down syndrome Identify the disorder and explain how it is expressed in a person and inherited. Down syndrome is a chromosomal disorder that includes a combination of birth defects. Affected individuals have some degree of mental retardation, characteristic facial features and, often, heart defects and other health problems. Down syndrome is caused by extra genetic material from chromosome 21. If you were the parent of a child with this disorder, with which question would you bemost concerned? How common is Down syndrome? How would you find the answer to your question? I would find information on my question through research. I would talk to my doctors and contact organizations set up to help people with concerns regarding Down syndrome. Sadly, Down syndrome is one of the most common genetic birth defects, affecting about 1 in 800 babies according to the Centers for Disease Control and Prevention. According to the National Down Syndrome Society, there are approximately 350,000 individuals with Down syndrome in the United States Choosea chromosomal disorder from the March of Dimes Foundation Web site.

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.
This could be due to carriers of the gene passing it on to their child, resulting in the child having two copies of the gene - one inherited from each parent - and manifesting the disorder. It is also possible for new mutations to occur in the child that cause the disorder, even if the parents do not carry the gene for it.
antisocial personality disorder
It is not possible to explain a false proposition.
An explanation of an isoimmunity disorder is a condition where an individual gains immunity against the foreign cells of another individual of the same species.
Even though the child has Down syndrome, he or she still is intelligent.
