She wasn't perfect due to the Wolvrine sample they had to work with.
Because of the dna they had to work with they had to make X-23 a girl to
solve certain problems. We are all female to start with, it's the extra
chromasone that shows up that maks us male or female. A girls wrists and
forearms are a lot smaller than a mans allowng for only 2 claws. It was
a surprise to the scientests when the foot claw showed up. To stimulate
the growth they removed the budding claws, which then grew back to full
size and they were then able to bond her with the adamantium.
