Explanation

XXY is Klinefelter's syndome. It is described as an inequality in X chromosomes where a male (dubbed by inheriting a X chromosome) also inherits an extra X chromosome, giving them female qualities. This can include a more slender shape, more refined hips, breast development, absence of facial hair, etc.
