This is fascinating. You say mammalian, but I'm guessing the vast majority of this sort of research has been on mice and placental mammals? I'm curious how different the mechanisms are in marsupials, since they seem to handle histrones somewhat differently. I know several groups are trying to clone marsupials, and this sort of research seems like it may be relevant.

(I would not be surprised if an echidna managed to commit parthenogenesis some day. Monotremes seem to think they're still back in the Cretaceous and don't even have a SRY gene.)

Yeah, most research has focused on placental mammals. Marsupials do things similarly though, see for example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6379045/

But I am not sure about monotremes.
