Quizplus · Accepted Answer

Studies have shown that there is no single gene responsible for autism, but rather multiple genes that contribute to its development. Additionally, there is evidence that environmental factors can play a role in the expression of these genes. Therefore, the most likely cause of autism is a combination of multiple genes and environmental factors.
