Is YY possible though? Never heard of that one.
Normally no, since one gonosome comes from each parent: The mother (XX) and the father (XY).
If somehow a series of unfortunate meioses occurred to create a zygote that had two Y chromosomes and no X chromosome, the foetus would absolutely not be viable, since the X chromosome contains many essential genes, while the Y chromosome is a truncated version that has less than half the information
There are situations that occur during fertilization, if the egg somehow loses it genetic material, the sperm enters the egg, but it duplicates its own half genome to form a 46 pairs but this is abnormal, because the gene pattering and also epigenetic silencing is different from males and females, so it forms abnormal mass of tissue called a mole; it can be partial or complete, one of the types can become a rare form of cancer
TIL meiosis gone wrong can cause a cumshot to give you cancer.
Thanks, internet stranger!
Interesting how they call this child a “boy” if the karyotype and genitalia are so ambiguous. Like, why???
A three years old apparently male child was referred to Anhui Provincial hospital with a complaint of undifferentiated external genitalia.
It might just be that that’s what they’re registered as, or how parents referred to them, I guess?
Well, the child is three years old and certainly has no concept of gender/sex. So how and why is someone apparently assigning gender and sex to this child? Why not just keep it neutral? Especially in context of forced gender and sex assignations as well as intersex child mutilations. Shouldn’t we be much more careful in this context not to force our biases and weird ideas of gender/sex onto children?!
