When does human life begin?

B. Human Life begins @ Conception.

I am pro-choice

My answer is letter B. It is the process of becoming pregnant involving fertilization or implantation or both. It is the beggining of life, if sperm does meet and penetrate a mature egg after ovulation, it will fertilize it. When the sperm penetrates the egg, changes occur in the protein coating around it to prevent other sperm from entering. At the moment of fertilization, your baby's genetic make-up is complete, including its sex. Since the mother can provide only X chromosomes (she's XX), if a Y sperm fertilizes the egg, your baby will be a boy (XY); if an X sperm fertilizes the egg, your baby will be a girl (XX).

Simplifying a complex issue usually doesn't end well.
I'm not touching this one.
