There isn't one. Gender is determined at conception and can't be changed.
Gender is not decided by the moon.
feemale narwhals have babys
There is no such thing as a gender predictor you will need to wait until the hospital discloses the information to you on her next scan, this will be the point in which you can determine the babies gender.
No. Gender is determined at the moment of conception by which sperm reaches the egg first.
You can find a same sex mod that allows the same gender to have babies.
They might cause a fight, if same gender, If not the same gender, the they will (most likely) have babies, and when a female hamster has babies, you have to help the babies come out. And if you touch the hamster babies AT ALL, the mother will eat them. I don't recommend buying another hamster.
your babies blood can.. not your blood nothing in the mothers blood indicates the child's gender
