Solution

Baldness is typically considered a sex-influenced trait, not sex-limited. A sex-influenced trait is one that is expressed differently in males and females due to the influence of sex hormones, while a sex-limited trait is expressed in only one sex. In the case of male pattern baldness, the trait is influenced by male hormones (androgens), which is why it is more commonly seen in men, but it can be inherited and potentially expressed in women too (though less commonly).
