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).

When the trait is on the X-chromosomes what is it called?
It is a sex-linked trait. Genes only found on the X chromosome can result in sex-linked traits. In humans these include hemophilia and color blindness.
What is the opposite of independent assortment?
Linked gene inheritance. In humans, it is called x-linked inheritance; sex-linked inheritance is when the trait is carried on the X chromosome.
How many genotypes are possible in a pedigree of sex linked traits?
xx = normal female x- x = carrier female x- x- = female which has the sex-linked trait xy = normal male x- y = male which has the sex-linked trait
How do you use the words sex-linked gene in a sentence?
Sex-linked genes, genes found on one of the sex chromosomes (X or Y) but not the other. Most sex-linked genes are X-linked because the female chromosome is longer.
If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
Which parent passes autism?
Autism is believed to be genetic, it's more strongly linked to the father but can be a result of both parents genes. There are theories that Autism is not just linked to specific genes but to pairs of genetic mutations from both parents, that when paired result in Autism.
What type of mutation causes autism?
The mutation that causes Autism is a rare genetic mutation. There are three different genes that are linked to the cause of different disorders on the Autism Spectrum.
Can high levels of lead in children lead to autism?
While high lead levels are linked to mental retardation and central nervous system damage in infants and children, they have not been specifically linked to autism.
Who Does you have autism?

Why is autism considered a genetic disorder?
Autism is considered to be a genetic disorder because it is caused by a persons genes. It's linked to a number of individual genes and genetic mutations.
Is klinefelters syndrome autosomal or x- linked?
X-linked
How kids have gotten autism from vaccines?
They haven't. It turned out that the medical study linking autism to vaccines was a hoax!!! The doctor responsible lost his medical license. The medical community has rejected that study, and doesn't believe autism is linked to vaccines.
Is fragile x like Autism?
no Added: Fragile X is like autism in that the condition can be a spectrum disorder, no or mild symptoms to severe symptoms. Fragile X is Genetic, the genetics of Autism are still being determined. Fragile X can be diagnosed any where by any doctor by a simple blood test, Autism is a subjective diagnosis based on evaluations and observations.
