I'm pretty sure that there are 3 ways?

Well, the main thing is that the offspring's genes will be half from one source and half from another source, rather than being almost an exact clone of its parent in asexual reproduction.
Another way might be crossing over during meiosis in which, basically, some genes go to other chromosomes and causes a mutation.

well each sperm contains one set of DNA or chromosomes, and there are several possible variations (each one to a different sperm cell). Also, in meiosis, crossing over occurs. And the law of independent assortment defines the fact that there can be several different types of DNA or chromosome combinations.
Lastly, you could say something about how in meiosis during metaphase, when the homologous bodies pair up, you don't know which way they're going to end up going- one side or the other before the cell splits into 2 and then 4.

each parent only gives one chromosome to the gamete
i don't know about the other ways
