The above diagram shows the developmental stages of the mother's egg cell and the fa-
ther's sperm cells. It also illustrates the transfer of chromosomes, packets of genetic infor-
mation, carried by the sperm and egg.
Chromosomes from the mother and father determine all the characteristics a person will
possess in future. Even while a human being is still no more than a fertilized egg cell in the
mother's body, all features such as eye color, blood group, facial shape and bone structure
are determined.
From the moment an egg is first fertilized, all events concerning all
the biochemical and physical developments that will give a human
form to the growing embryo take place under the control of the blue-
print in the DNA.
Prof. Phillip E. Johnson refers to the flawless nature of the system:

Instructions in the fertilized egg control embryonic development from
