when the Control Room appears, by pulling down the Level menu.
Tutorial Mode: The embryo has only one mutation, the left arm is an insect arm. (This is the mutation shown in the tutorial movie on the CD-ROM version)
In addition, when you select a mutated cell with the cross hairs, the window not only shows the body part that is mutated, but also the chromosome and the gene on the chromosome with the mutation.
Beginner Mode: The embryo has only 4 mutations. They are all mutations with visible effects (that is, they appear in the extrapolation when you hit the embryo test button and select extrapolation)
And as in tutorial mode, when you select a mutated cell with the cross hairs, the window not only shows the body part that is mutated, but also the chromosome and the gene on the chromosome with the mutation.
Intermediate mode: This is the same as the old "Basic" mode. The embryo has 10 mutations. Some do not have visible effects, but all are simple mutations.
Advanced mode: This has not changed. The embryo has no initial mutations, but mutations occur as time passes. All kinds of mutations can happen, not just visible ones. The nutrient media levels fluctuate, and infections will happen.
