UnpledgedCatnapTipper@piefed.blahaj.zone 22 hours agoIf you’re rewriting DNA to make people into dinosaurs, then changing a Y chromosome to an X chromosome and making the changes express themselves seems downright simple by comparison.

also dinosaurs/reptiles generally dont use the XY system like mammals do. they have a ZW system to determine sex, and for some its temperature based. ZZ for male birds, and ZW for female birds(ZW means 2 different chromosones, and ZZ is too similar ones).
the closest in between would be monotreme xy , they behave more like ZW eventhough they have 10sex chromosomes.
