      Can someone please explain how individuals can have genotypes such as XXY and XO? I am having trouble finding anything on it. Thanks, Chuck

      If the chromatids in meiosis don’t split you can have the same gamet that caries no sex chromosome(leads to XO-Turner) or 2 sexual chromosoms(leads to XXy-Kleinefelter)
