Could I have someone or some people explain Unicorn genetics for colors for me? I'm trying to understand it but I'm getting confused. Thanks!

Have you looked under the Help tab at the List of Skins and List of Genes? The List of Genes can show you the gene power of each of the genes, letting you know which would be dominant, while the list of skins is an easy way to see what each color/pattern combo looks like.

I know that, but what I don't understand is how the genetics work on the unicorns tabs. Like determining weather the gene on the mother or fathers side is dominent/recessive and how someone could tell this with the unicorn being geneticlly tested.

The genetics system is the same for all species, although some species have different genes. If you hover over a gene, you'll see that it reads "Power: 60" or "70" or some other number. Of the two genes the pet inherits from mother and father for each body part, the dominant gene is always the one with the highest number. A gene with power 90 will always manifest over one with power 60. 

If you're asking which of the parents' genes will be passed on to the offspring, I'm under the impression it's a 50/50 chance for either gene in each set. 

Okay, what if both genes say 40? or have the same number?

That doesn't happen, unless they are both the same gene. The game has it set that one gene is always stronger than the other. If a pet does have twice the same gene (like two times Black), it's random which one turns green (is the "dominant"). It doesn't make a difference though, since no matter which Black gene is dominant, the result is the same anyway.

Also, if you look at the List of Skins graphic, the right-most pattern is the most powerful (always dominant) and the left-most pattern the least powerful. In the same way, the top colour is the most and the bottom colour the least powerful. So, getting a Silver Gray Unicorn is the most difficult in this respect, since BOTH colour genes have to be Gray and BOTH pattern genes have to be Cream. As soon as one of the genes is another one (say Black or Striped), the pet will always show that colour/pattern.

This also helps in determining what genes a pet might have, if you don't have genes researched. If your pet is for example a Buckskin Zebra Unicorn, you can already say that the dominant (so the shown) genes are Bucksin colour and Striped pattern. You still don't know the recessive genes, but since Buckskin and Striped are both pretty weak (notice, how far down/left the picture is in the chart?), you now know for sure, that the recessives are either again Bucksin and Striped OR the weaker alternatives, Cream and Gray. 

Hope this makes sense  xD

That won't happen with different genes. The only way for both of the same category of genes to have the same power is if they are the same gene. So, if both genes are for chestnut, then the Unicorn will be a chestnut. However, if the Unicorn has one gene for chestnut and another for white, the Unicorn will be white because that has the higher power genetically.

Okay, I think I'm getting it now. Haha. I'll look into things and see what I come up with!
