Butterflies have an x-y sex determination system that is different from that of flies or humans. female butterflies may be either xy or xo, 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 during the first mitotic division might have produced this unusual-looking butterfly.
