This takes place in the short future, in the year 1989. You are one of those mad scientists that invented "Zygotes", genetically-modified organisms, created to be the cutest pets for children. Now that you have a few of them, you will try to understand which gene codes for each characteristic (hair color, muscular body, horns etc...) so that you can cross-breed them and try to obtain Zygotes you can sell at higher prices, or meet special customers requests.
