(Excerpts, Ethics and Human Dignity, 2010)
When does life begin? Conception happens when a male cell (spermatozoon) fertilizes the female cell (the ovum). It then becomes a zygote. This zygote contains the full genetic code of twenty-three pairs of chromosomes. Afterwards, the zygote undergoes the process of cell division. The zygote then grows then moves through the fallopian tube and gradually implants itself in the uterine wall.
