Breeding Programmes

So I'm relatively new to PZ, but I've been loving it. I have one zoo I'm playing on Challenges mode (in Year 37, doing very well) and I've just started up a new sandbox zoo that I want to use to run breeding programmes.

So I was wondering, how do you guys run yours? What genes do you look for, how do you make matches, and what's your process? I've seen a lot of talk about various animals having different colourations (eg albino), and I presume you can select and breed for those traits. I'm looking for tips, tricks, or just general advice and how-to!
