    I was looking for a detailed account of human procreation.

    Does sperm contain the preliminary information that tells to host how to form the embryo, i.e. the first cells, blood, bones, organs etc.

    Sperm is a cell correct? So it carries the information that details how other cells are created?

    Do polypeptides make up tissue and if so what happens after polypeptide synthesis? Do the polypeptides sequence differently to create tissue, etc.

    Or is everything in the human body made up of cells and the initial sperm cell has the information for the creation of all the other cells?

    The sperm and the egg each contain half of the genome of the resulting organism. Although, the egg also contains several maternal proteins that will determine how the embryo develops immediately after fusion, because it takes some time for the embryo to begin making its own proteins.

    The body is mostly made of cells, but obviously not all cells. Tissues are made of cells and extracellular matrix which changes depending on the cell type.

    So the DNA in the sperm and egg contain all the information for blood, bones, tissue, skin, teeth etc. This information is combined to tell the host to start creating all the initial cells that form the embryo. Then the embryo begins making its own proteins?

    I guess what I was really trying to ask was in regards to cellular differentiation. http://en.wikipedia.org/wiki/Cellular_differentiation

    I was confused here. I was looking at the information or cells being carried by and/or created by zygote formation; whether there were preliminary cells that had to be in existence. But cellular differentiation explains where I was getting held up.

    Obviously. The sperm and the egg contain the information to make the Mesodermal, Ectodermal, Endodermal cells. Which further make different organs and tissues responsible for the human body overall.
