Ok, I am confused here!

How many solid ball of cells does morula form? Rea's bio is saying 16 or so blastomeres, but different textbooks say 32 cells. I remember from achiever saying smth about 8 cells

You don't have to worry about this as far as the DAT goes. Having 16 or 32 blastomeres in a morula is simply a result of 4 or 5 mitotic cleavages. I don't remember seeing an 8-celled morula in Achiever, but believe it does quote an example of the same that contains 32 blastomeres. Hope this helps clarify.
