Yes I am not a Newbie but I want to know this.

Can you breed a 4 vis?
Any help would be appreciated. I really want to know this because I am planning a breeding project.

If you're asking if it's possible certainty. If you're asking if theirs an easy way to do it, no. I have a few tables in my breeding threat that show how to go about breeding one.

1. If you have a female with 3 genes
Ex The Black Lup in my Hatchery

2. Use a LGM Lesser Genetic Mutinater and get a 4th gene

3. Generate using a Enh Lup Essence a male with the same genes

Would breeding them give me a 4 gene vis?

Well the black female in your hatchery isn't captured so you won't be able to use a genetic mutator on her. However, hypothetically, if she was captured and you mutated her to get a 4th gene and you breed her with a male that carried the same genes, with enough breeding you'd eventually get a 4-vis child.

However when both parents only carry a gene there's only a 25% chance of the gene being visible, so only about 1 in 256 will show all 4 genes.

So I could get a 3 vis with the girl?

yes, if you generated a male for her you would want a boy that shows either the same gene she does(which will guarantee the children always showing that gene) or show another gene that she carries (Making jeweled horns and the other gene a 50% chance of showing every time they're breed) So getting a 3 vis out of them would be roughly 1 in 16

Okey thanks for your help.
