At fertilization the egg and sperm cease to be. They become a one celled blastocyst

Better brush up on your terminology. There is no such thing a "one celled blastocyst". "Blastocyst" refers to the many-celled stage where the embryo has differentiated into two different types of cells, in two separate regions, one of which will become the placenta and the other of which will become the fetus.
