Before Carter's birth, Will Settle had a son with his ex-wife. He thought he would continue to give birth to a boy like other families in the family. By the time she was born by her second wife, the Will Settle family had burst into joy.

"Actually, I was shocked, I thought there would be one more kid. My mother always wanted a granddaughter and she was crazy to get this good news," Will said. The humorous young father said he wanted his daughter to be strong to deal with all the men in the family so he chose Carter's name.

In humans, the sex of the fetus depends on sperm. The reason is that a woman's egg contains only one X chromosome, while the man's sperm contains an X or Y chromosome. In it, the sperm contains an X chromosome that encounters an X chromosome. conceiving a girl. The Y chromosome-containing sperm meets the X chromosome egg to give birth to a boy. Therefore, the sex of a child is decided right at the time of fertilization.
