Autism can be inherited from a parent with genes for autism. It can also be the result of a gene that mutated.
Perhaps there is a better word to describe the biological process that might be involved in changing gene structure? Instead of "mutated" which is connected with "mutant", "mutilated", "mutation", we could talk about "differentiated" which leads to the words "difference", "different" and "differentiation".
We can then reserve the word "mutated" for those people born resembling a "Shrek" gone all wrong, and not those with perfectly acceptable normal variations within the wide parameters of what is consider typical humanity. It would not be sensible to include people who are double-jointed, left-handed, mixed lobed, beak-nosed, pidgeon-toed, knock-kneed, butt-ugly, or phobic about so-called disabilities, as all being mutants. I think it would be much more clever to consider them pretty much part and parcel of run-of-the-mill humanity.
Neither. Aspergers syndrome may be hereditary and it is usually noticeable early on in life, but that is not to suggest that there is something defective about Asperger's syndrome. The DSM IV classifies it as a pervasive developmental disorder. There have been studies showing clear genetic factors, and it's more common in males as a father tends to pass the traits on to his son. Aspergers may be a genetic trait that causes a social/developmental disorder, but it also has positive benefits associated with it. Quite commonly people who develop Aspergers have extreme difficulty reading other people's reactions or realizing when their behavior is inappropriate, but they also often develop very astute minds and tend to score above average on IQ tests. Asperger's labeling as Autism is also somewhat controversial.
Autism itself is not genetic however the genetic cause behind it is. There are several genetic disorders that can cause autism, such as fragile x, metabolic disorders etc. Everyone and every family is different. What may have caused autism in your family may not have caused it in the next. This is also why each autistic child can vary so much in functioning and even physical issues as well. Each genetic disorder has it's percentage and probability of having more than one autistic child as well. The only way to truly tell where the autism in your family came from is genetic testing to find out the cause behind the disorder and genetic counseling to determine the best course of action and go from there.
The genetic causes of autism are unknown, but it is certain that no single gene is the cause. It may in fact be caused by combinations of as many as thousands of genes, some of which in different mixtures are even strongly beneficial. Some of these genes may be recessive while others are dominate.

A gene is recessive when?
A gene is considered recessive when its effect is masked by a dominant gene in a heterozygous individual. This means that the trait associated with the recessive gene is only expressed when an individual inherits two copies of the recessive allele.
You can be a carrier of a recessive gene as part of your?
You can be a carrier of a recessive gene as part of your genotype.
How many copies of a recessive gene does it take to overpower a dominant gene?
It takes two copies of a recessive gene to overpower a dominant gene. This is because a dominant gene will be expressed over a recessive gene in individuals who carry one copy of each type.
A gene whose code is not expressed unless a similar allele is present is called an?
recessive gene
If a genetic disorder is carried on a recessive gene which if any will have the disorder?
If a genetic disorder is carried on a recessive gene, offspring will only have the disorder if both parents have the recessive gene.
Is autism caused by a dominant gene?
yes , autism is caused by a dominant gene
Which of these is a gene that does not express itself and is concealed by the presence of another gene of the same trait?
A recessive gene is a gene that does not express itself in the presence of a dominant gene of the same trait. When an individual inherits two recessive genes for a trait, the recessive gene will be expressed.
A gene is recessive when?
A gene is considered recessive when its effect is masked by a dominant gene in a heterozygous individual. This means that the trait associated with the recessive gene is only expressed when an individual inherits two copies of the recessive allele.
Genes that are only seen when paired with a recessive gene?
Recessive genes are only expressed when an individual has two copies of the recessive allele. If an individual inherits one dominant allele and one recessive allele for a particular gene, the dominant allele will be expressed phenotypically. The recessive allele will only be expressed if the individual inherits two copies of the recessive allele.
Is leukemia a recessive gene?
recessive.
A gene that can be masked by another gene is called?
A gene that can be masked by another gene is referred to as a recessive gene. This means that the trait associated with the recessive gene is expressed only when two copies of the gene are present.
What gene won't display its trait in the prescience of a dominate trait?
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
You can be a carrier of a recessive gene as part of your?
You can be a carrier of a recessive gene as part of your genotype.
The weaker of two genes is called what?
The weaker of two genes is called the recessive gene. In the presence of a dominant gene, the recessive gene is not expressed in the organism's phenotype.
When both parents contribute to the gene pair are recessive the pair is referred to as the?
The gene pair is referred to as homozygous recessive. This means that both copies of the gene are recessive, resulting in the expression of the recessive trait.
How many copies of a recessive gene does it take to overpower a dominant gene?
It takes two copies of a recessive gene to overpower a dominant gene. This is because a dominant gene will be expressed over a recessive gene in individuals who carry one copy of each type.
Which type of gene or gene combination can be present in a generation without affecting phenotype?
A recessive gene or gene combination can be present in a generation without affecting the phenotype if it is masked by a dominant gene. This means that the trait associated with the recessive gene will only be expressed if an individual inherits two copies of the recessive gene.
