Chapter Text
Basic Story Summary
Marinette takes Adrien’s miraculous due to his behavior in class and his advice to her to ignore lila. Kagami is given the ladybug miraculous while Marinette takes up the black cat. During this time Jagged brings her a crocodile egg and tells her that it’s Fang’s child and that Fang personally chose this one for her. He aids her in getting a permit so she can keep it and provides her the supplies she will need for both hatching it and raising it. Her parents at this point have kicked her out and she’s living in Fu’s old shop with Markov, whom Max had kicked out due to a difference of opinion. She has branched out her commissions shop and begins offering customized teas. She proceeds to open Fu’s shop as a tea shop. Nettie (as nettie) gets hit by the akuma Family Ties and is sent to batman’s team in the middle of the night on their patrol route, basically right on top of bruce. At some point it is revealed that Joker cloned himself and Bruce and due to some weird science thing, nettie turned out to be a girl. Joker didn’t want a girl so he sent her off. She ended up with Tom and Sabine.
Cloning Info
To create a female clone from a man you could take his cells and turn off the Androgen receptor genes. So the person will develop as female and will have Androgen Insensitivity Syndrome. A sterile woman with XY chromosomes.
If you're willing to loosen your definition of "clone" just a little bit, the same technique can be used in either direction.
As noted in another answer, duplicating the X chromosome from a male, while deleting the Y, has potentially serious problems, in that the result will resemble inbreeding in terms of genetic duplication for any genes carried on the X. Further, there isn't a practical way to create a Y from an X to go the other way.
So just adopt part of Mother Nature's method -- bring in donor chromosomes from an unrelated male (in the case of the male clone from female original) or female (vice versa). All other genes will be identical to the "parent's" genome, and by controlling which X is active (as noted in another answer, only single X is active in a female), the female clone from a male "parent" can be as identical as possible, while the male clone from the female "parent" will also be as identical as a male can be.
There is another option (not necessarily a good one) for cloning a female from a male "parent" -- just delete the Y and leave things alone. This will give a female child with Turner's Syndrome, most of the effects of which can be countered with hormone supplements at appropriate development stages. Probably unethical, but possible…
Saltwater Crocodile info
The eggs are roughly the size of a man’s palm and the hatchlings are about the length of a man’s hand
