Can anyone suggest some resources that explain the genetics of bilateral and mosaic gynandromorphs?
Thank you,
Tim

Hi Tim - here is the Wikipedia explanation - which is pretty accurate relative to how it works in leps.
The cause of this phenomenon is typically, but not always, an event in mitosis during early development. While the organism contains only a few cells, one of the dividing cells does not split its sex chromosomes typically. This leads to one of the two cells having sex chromosomes that cause male development and the other cell having chromosomes that cause female development. For example, an XY cell undergoing mitosis duplicates its chromosomes, becoming XXYY. Usually this cell would divide into two XY cells, but in rare occasions the cell may divide into an X cell and an XYY cell. If this happens early in development, then a large portion of the cells are X and a large portion are XYY. Since X and XYY dictate different sexes, the organism has tissue that is female and tissue that is male.[9]
In a perfect bilateral gender-blender, the problem arises during the initial cleavage of the fertilized ovum, and you end up with one half male, one half female split right down the middle.
