A sex-limited trait is a characteristic that is only expressed in one sex, either male or female. This trait is typically controlled by genes located on sex chromosomes. For example, male pattern baldness is a sex-limited trait that is more commonly seen in males than females. In this case, the trait manifests differently in males and females due to the influence of sex hormones and genetic factors specific to each sex.
The traits which are influenced by the sex are called sex limited traits. These traits are just limited to one sex, either in male or female. For example, the genes for pattern baldness are present in both the sexes but expresses more in male as compare to female.
