Genetics do have some impact upon not only our physiological appearance but also our psychological and neural profile. It is more likely that an XX genotype male (yes, they do exist) will have not only less masculine phenotype, but also exhibit a more feminine psyche. Voodoo:When you see a picture of an X shaped chromosome, it is in the first stages of mitosis and has just finished duplicating itself. Prophase is not the stage of PMAT at which duplication takes place! Prophase is the stage at which the base pair strands split! Isn't the mitotic stage you're thinking about Anaphase, after duplication during Metaphase?
