No, you cannot have autism if your parents do not have it. Autism is a neurodevelopmental disorder that affects communication, behavior, and social interaction, and it is not something that can be inherited or passed down from parents to children.
Autism is caused by a combination of genetic and environmental factors, and it is not caused by any single gene or gene combination. Genetics may play a role in autism, but it is not inherited directly from parents. It is more likely that autism is caused by a combination of different genes that interact in complex ways and are passed down from generation to generation.
The environmental factors that may contribute to autism are still not well understood, but research suggests that environmental exposures such as toxins, medications, and other factors may play a role.
It is important to note that autism is a spectrum disorder, meaning that it affects individuals differently and no two people with autism will have the exact same symptoms. Therefore, it is impossible to predict if someone will or will not have autism based on their family history.
In conclusion, autism is not something that is inherited from parents to children, so you cannot have autism if your parents do not have it.
