When you hatch a chao from the black market or the garden, you won't have any idea what the chao will look like or what its stats will be. Supposedly, this is the only random thing that happens in Chao Genetics at all. So, how does it all work? What do you, the player, need to know about chao genetics in order to get the best and coolest-looking chao out there?
Chao Genes
Chao may seem like simple creatures at first, and they are in behavior and how they need to be taken care of, but behind all those cute dances and instrument playing lies something much deeper. When you mate a regular chao together with another regular chao, the results will be a baby regular chao. This has been tested over and over and the results do not differ (the case may be different for those who own a "rainbow" chao, but I have never seen one of these before or have obtained any solid proof that these chao exist). When a regular chao is mated with any solid-colored chao, the baby has a 50-50 percent chance of being either of the two - the solid-colored chao or the regular one. Through past experiments I have actually found the solid-colored chao to be dominant, so you have more of a seventy-five percent chance of getting a colored baby over the twenty-five percent chance you have of getting a regular baby that also holds the genes of the colored parent (think brown eyes/blue eyes).
The Links in the Chain
So how will those genes come to play in the future? Pet your baby regular chao - the offspring of the colored/regular parents - and you will get something that looks like the blitz chao. If you get another baby chao from a set of parents exactly like the ones the first blitz chao was born from (so that you have two), and mate them together, chances are very high the baby will look both parents - like another blitz chao. This, my friends, is the beginning of a new chao species.
Let's move on to two-toned chao. So you mate a pink and purple chao together and get a pink chao. You pet it, and it turns pink AND purple. The baby chao obviously has the genes of both parents. Now, get two other chao of different colors and get another two-toned baby (try yellow and green). Once the baby is born, there are now two two-toned chao: A pink and purple chao and green and yellow one. What happens when you mate them? Well, from pictures I've seen, you have a chance of getting a chao that's all four colors. You're probably thinking, "Wow! I want one!" But think harder - You have higher chances of getting a baby that's just two colors, either pink and purple or yellow and green. And then you have even higher chances of getting just a pink, purple, yellow, or green chao (but don't take my word for it... these conclusions I've come to are just guesses. I've never actually tried mating these chao together to get the results. I haven't even been able to successfully obtain a two-toned chao).
Chao from one generation will pass on thier genes to their offspring, which will then continue the "cycle" (or link).
Percentages?
I'm going to work an example of genetics with two sets of chao: A shiny green Chao and a regular Yellow one. Now, think of the possibilities... these are the chao that can be obtained if we mated these two chao over and over: A shiny green Chao, a regular green Chao, A shiny yellow chao, a regular yellow Chao, a shiny green/yellow two-toned chao, or a regular green/yellow two-toned chao (some colors work for two-toned chao, others don't. Yet another example of how complicated chao genetics can be 0_o). The "shiny" gene is always dominant, and the "green" and "yellow" genes are recessive. I've worked on a sort of Punnett square for these sets of traits, and here are my results for the percentages of obtainable chao from those two parents:
Green - 11%
Yellow - 11%
Green/Yellow - 11%
Shiny Green/Yellow - 22%
Shiny Green - 22%
Shiny Yellow - 22%
Whoo... those figures actually look convincing, huh? Hehe. Below are a few more figures you can work with if you're planning on becoming a real chao breeder yourself. The offspring chao are the ones with the percentages next to them.
Mating: A regular Chao with a colored chao.
Regular Chao: 25%
Colored Chao: 75%
Mating: Any two two-toned-approved colored chao.
Two-toned Chao: >25%
Single-colored (ex: Yellow)Chao: ~37%
Single-colored (ex: Green)Chao: ~37%
Mating: A shiny white chao with a regular chao.
Shiny White: 25%
White: 25%
Regular: 25%
Shiny Regular: 25%
Mating: A regular chao with a regular chao.
Regular: 100%
Mating: A jewel chao with a shiny chao.
Transparent Chao: 100%
Note about the Transparent Chao: You can actually get different-colored tranparent chao depending on which you colors you mate together.
Conclusion
Chao genetics can be tough, but all you need to know is a few percentages and which chao colors are dominant and recessive. Once you get the hang of it, you'll be able to follow the links in the chain of colors, and chao breeding will become easier. The only thing you're going to continue to need is a lot of time for experiments. Chao raising may be simple, but sometimes it is no easy feat.
