I wonder: Since fertilized eggs are citizens, how about unfertilized eggs? How about sperm?
At fertilization the egg and sperm cease to be. They become a one celled blastocyst with the same DNA that life will have till he/she dies. Be it at 93 years or 93 minutes. At this one cell stage the sex is known, as well as all the info that can be gotten from a DNA test on you or me.
