Detailed explanation-1: -Human X and Y chromosomes determine the biological sex of a person, with XX specifying female and XY specifying male. Although the Y chromosome contains a small region of similarity to the X chromosome so that they can pair during meiosis, the Y chromosome is much shorter and contains many fewer genes.
Detailed explanation-2: -Genotypic sex refers specifically to an individual’s two sex chromosomes. Most people have either two X chromosomes (genotypic female) or an X and a Y chromosome (genotypic male).
Detailed explanation-3: -The cells descended from that cell, instead of being XX (female), are XO (male). Because there are no sex hormones in insects to modulate such events, each cell makes its own sexual “decision.” The XO cells display male characteristics, whereas the XX cells display female traits.
