"It has to do with deciding the 0 or the 1 the x or the y,"
The sperm from a father(paternal) chooses the sex of the child, because the male carries both the X and Y chromosomes, where as the female carries 2 x chromosomes. This works for most mammals, insects, and plants. However it is opposite for birds.
The Mother(Maternal) has two x chromosomes.
"Both males and females retain one of their mother's X chromosomes, and females retain their second X chromosome from their father. Since the father retains his X chromosome from his mother, a human female has one X chromosome from her paternal grandmother (father's side), and one X chromosome from her mother."
This is an example of fractal logic.
"And he took bread and, having given praise, he gave it to them when it had been broken, saying, This is my body, which is given for you: do this in memory of me."
