Did they ever specify any conditions he had? I see zero evidence that it was hereditary. Just because something "doesn't look great" doesn't mean it is true. It's not supposed to look good. It's supposed to look bad. The film is not trying to absolve Jenny in that moment.

Seemed to be a general learning disability. A parent with a learning disability is more likely to have a child with a learning disability. It's not necessarily hereditary, and I'm not saying someone with a learning disability can't have a gifted child. But given the whole set of circumstances, it just compounds the likelihood that Forrest is not Forrest Jr.'s biological father. It's not impossible that he is, but it's far from a certainty.
