Each school is different, so you should contact your specific schools to find out. Some schools told me that they would accept a physiology course, while other schools said that I had to take the typical general biology 2 course (I ended up taking general bio 2 just to be sure that I pleased everyone). I recommend that you email the schools so that you have their response in writing, just in case they tell you one thing and then contradict themselves in the future.
However, if you are able to take A&P in addition to the general bio course, then it will make your application even stronger and prepare you better for dental school. I would've taken both if I had the time.
