At this point, no one can say for certain that autism is even a genetic trait, as the causes are not fully known or understood.
There are certainly some genetic factors that seem to play into whether someone will develop autism, but it isn't as simple as dominant/recessive genes. Environmental factors, diet, vaccines, and other variables have also been suspected as autism causes or triggers.
If it were strictly a genetic disorder, it would be a recessive trait. If it were dominant, the number of people with autism would be much greater. The logic behind that is probably beyond the scope of this question.
The causes of autism are still unknown. There does seem to be some correlation to certain factors, but whether this is simply a correlation or a real risk factor is currently unknown. So far, it does appear that genetic inheritance is a factor, there doesn't appear to be an "autism gene", rather, it may result in a complex interaction of various genetic factors. And, genetics may not be the sole cause. For now, we really don't understand autism at all.

No. Autism is a neurodevelopmental disorder

Infantile Autism is when a baby or toddler (an Infant) has autism.
Basicly, autism is something you are born to have, not something that you could grow into. So, adult autism, means that a child with autism grows up and become an adult with autism. However, if you didn't find out that you have autism until you are an adult, then your autism must be the mild kind on the entire autism spectrum.
Biologial. Autism is neurodevelopmental. There are hereditary and genetic ties to autism.
No, Jedward do not have autism.
No, Macy Gray does not have autism, although she does shows for autism causes.
Autism can be inherited from parents with genes for autism. Autism can also be the result of the spontaneous mutation of a gene. It is suspected that a person with the genes for autism might need an environmental factor (in the womb or shortly after birth) to trigger the development of autism.
Autism is not traditionally x-linked. If it were x-linked dominant, all females of an affected father would have it (since they always get one x from their fathers). If it were x linked recessive, then it would skip a generation and NO male sons of an affected father would have Autism. There is evidence that there is a relation to sex, given the increased ratio of affected boys to girls, but it's a complicated mix of genetic and nongenetic causes (i.e. imprinting of genes, comorbid diagnoses).
he does have autism
No, autism is rare and not contagious.
Autism is not an intellectual or a psychological problem. Autism is a neurological difference.
