The lack of a Y chromosome determines the male sex in the XX female and XO male types of sex determination. In this arrangement, males have one X chromosome (XO) and no Y chromosome, whereas females have two X chromosomes (XX). In this particular sex determination method, the Y chromosome's presence or absence is critical in determining the sex of the offspring.
