You will be fine. When I applied I had not taken Genetics or physics 2, which are both requirements for the program at UF and I was accepted no problem.
If you have been making good grades in all of your science classes thus far ADCOMs can make assumptions about your future performance. For example if you had taken Bio1/2, GenChem1/2, and orgo1 and got A's, it would be safe to assume that you will do well in O2.
