SOLVED:Butterflies have an X-Y sex determination system that is different from that of flies or humans. Female butterflies may be either XY or X0, while butterflies with two or more X chromosomes are males. This photograph shows a tiger swallowtail gynandromorph, which is half male (left side) and half female (right side). Given that the first division of the zygote divides the embryo into the future right and left halves of the butterfly, propose a hypothesis that explains how nondisjunction du

The XX - xx

It’s not as simple as XX vs. XY. Sometimes things develop differently than you would expect from looking just at someone’s chromosomes, including in ambiguous ways that aren’t very obviously “male” or “female” at birth. Biological sex exists along a spectrum, not a simple binary. These are two quick examples of differences of sex development that don’t fit into the typical “male” or “female” buckets, but please note that this video barely scratches the surface of the nuance around this topic...

men have xy or yx chromosomes and women have xx chromosomes x linked recessive genetic diseases such as juvenile retinoschisis occur when there is a defective x chromosome that occurs withou 67416
