Explanation
In English grammar, the noun "genius" is specifically paired with the preposition "for" when it refers to a natural talent, strong ability, or aptitude for a particular activity or subject.
Genius for: Used to describe a natural ability (e.g., "a genius for organization," "a genius for mathematics").
Genius in: While sometimes used to describe a person's status within a field (e.g., "He is a genius in his field"), when talking about a specific skill or subject matter as an attribute someone has, "for" is the standard idiomatic choice.
Genius in/about: These do not typically follow the noun "genius" in this context.
