Not when all the incarnations are the same Doctor, and he is still alive.
In actual fact, thinking about it further, not only would genesis never happen in the first place, but the Doctor's history right from the very second episode would be very different and the 4th Doctor , or any other incarnation as we know them could and would likely be very different.
Plus, it's not like they'd ever actually really erase the Daleks.
