Medical Riddle?

Right! Is it even in supposition possible for a YY Chromosome child to occur essentially?Medical Riddle?
yes and no. A zygote could form in the bag of two nondisjunctions resulting in an egg near no sex chromosomes and a sperm with two Ys. the likelihood of those two events happening and that one sperm being the one to fertilize the embryo are totally, very small. The embryo would next be naturally abort early on surrounded by development.
Naturally? Not as a rule. The mother provides X chromosome contributions.
However, it is possible due to a rare genetic condition call chimerism.
This can create XY cells contained by the ovary, odd as it sounds, and it have a in one surrounded by a billion situation to create a Y egg cell.
No, If there is a Y chromosome next the child born will be male genetically. Even surrounded by the extremely rare skin of double conception where someone ends up next to a YXX combination the person will still be born mannish, but may appear to be female. And surrounded by this case the individual will be sterile due to the further chromosome.
Troy is right.
