If 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).
birds, reptile, seems more complicated than the mammal system.
the closest in between would be monotreme xy , they behave more like ZW eventhough they have 10sex chromosomes.
*Except for the Y chromosome. You’d have to somehow insert these genes and get them to be expressed
Seems they mostly have to do with development of testicles
