Sex Chromosome Abnormalities and Their Symptoms

Sex Chromosome Abnormalities and Their Symptoms

People are generally told that biological females have two X chromosomes while biological males have an X and a Y chromosome. However, it is just the presence or absence of a Y chromosome that researchers use to determine someone’s sex. If a person has a Y chromosome, they are considered to be a biological male and, if a person does not have a Y chromosome, they are considered a biological female. These distinctions exist because there are many sex chromosome combinations that are different from the two that are typically spoken of. XO Turner syndrome, sometimes represented by an XO,…
