Both sex-influenced and sex-limited traits are influenced by sex chromosomes. Sex-influenced traits are expressed differently in males and females due to hormonal differences, while sex-limited traits are only expressed in one sex due to anatomical or physiological differences. Both types of traits are dependent on the sex of the individual for their expression.
The biological sex of an individual with XY sex chromosomes in humans is typically male.
