Title: Fixed code error on p. 412 (DNA-class)

There's no DNA constructor with an int-argument as it is called in the crossover-function. So this code failed to compile (when you're lazy like me and just copied and pasted it).
I just removed `genes.length` from the constructor at the instantiation of `child`.

P.S. thanks for that great work. It's a pleasure to read through it.
