Are genius and insanity on the same chromosome?

The phrase "genius and insanity are on the same chromosome" is a metaphorical expression suggesting a link between high intelligence and mental illness. While some studies have explored correlations between creativity and certain psychological conditions, there is no scientific evidence to confirm that they share a genetic basis on a specific chromosome. Intelligence and mental health are complex traits influenced by a combination of genetic, environmental, and social factors. Thus, while there may be overlaps in certain traits, they are not directly linked on a genetic level.
