I don't know much about Ob/Gyn and Step 2 is forcing me to learn at least a little. I am stuck on moles. Complete moles. Since you folks know about these pregnancy things the most, I am asking for your help. If I should be asking in the USMLE forum, just let me know.
The Q/my problem: Robbins tells me that complete moles come from a sperm's haploid DNA developing in an empty egg. It then says, these completes can be 46, XX or 46, XY - all from sperm DNA from one duplicated haploid or two haploids from two sperm. What about one sperm's 23 Y DNA duplicating giving a complete mole of 46, YY? Why isn't that mentioned?
I am not sure if I am misunderstanding the genetics or if a 46, YY just doesn't "grow" past the "one cell" stage. Please help.
