So I look occasionally at the ads for joeys on this forum, and I often don't have a very good idea of what all the lineage stuff means. Could someone in-the-know write up a guide? For example, a recent post was talking percentages, used terms like "het" (heterozygous, I'm guessing?), and I couldn't make a lot of sense out of most of it. I'm not even looking into breeding, but I'm super curious about what it all means. It would also probably be super helpful for people who want to start breeding

I have a ton of this information on my website. There is just too much to create a sticky for it. If you have any questions while reading through, feel free to ask!

Start by reading the Breeding Page first, then go to each page on the pop out.
