I think the DNA does contain instructions for making the egg. For example, if executing the DNA instructions produces a human female, she'll be born with a lifetime supply of eggs, the developmental instructions for which were part of her startup DNA. Those instructions were definitely not part of the "cell soup", as is shown by mitochondrial donation assisted reproduction technology (aka 'three-parent babies'). |

Cells are factories, incredibly complex ones. DNA is a set of punches in a tape.
