Second Eye Color Gene

Alright, I'm finally back to it! This is an idea that I've kinda mentioned around in other posts, but I think that it's finally time to make it its own post. Many people are in support of the popular heterochromia gene, but I think it would be a waste to have a gene slot created only for heterochromia. This is where my idea comes in, the gene slot for heterochromia would have several other alleles that I'm about to propose as well. I would say that all of these genes would normally not be accessible through the mutation menu, but lemme know what you guys think.

First, the most dominant allele would be the "Normal Eye Color" allele. It's exactly what it sounds like, the creature will present what it's normal eye color would be. For example, if a creature has a black eye color allele and a blue eye color allele, the creature will present the black eye color because the black eye color allele is more dominant than the blue eye color allele. This is the only allele I think you would be able to find in the mutation menu similar to no melanism and no albinism, and it would automatically be unlocked.

After the standard allele, there would be the "More Melanin" and "Less Melanin" alleles. These are pretty standard and would either make the normally presented eye color darker or lighter respectively. Having blue eyes and the "Less Melanin" allele could create gray eyes for those who want that. 

The next most dominant would be the "Mixed Eye Color" allele. The primary inspiration for this allele is from hazel eyes which are generally considered a mix between brown and green. With this allele present, the nicheling will display the primary eye color alleles with incomplete dominance which basically just means that the two will present mixed. If a creature is homozygous for their primary eye color, then this allele would not present any differently than if the creature had the "Normal Eye Color" allele. (Side note: I wasn’t sure if the “More Melanin” allele was necessary seeing as it can also be achieved through having the “Mixed Eye Color” allele and a black eye color allele. Lemme know if you think I should keep it as two ways to get the same outcome or if there’s anyway you think I could differentiate them.)

Next would be the heterochromia alleles. I would like to propose both "Dominant Heterochromia" and "Recessive Heterochromia" alleles where the "Dominant Heterochromia" would have the dominant eye color on the right and the recessive eye color on the left and the "Recessive Heterochromia" would be vice versa. The only reason for the two different alleles would just to have more controllable variability for heterochromia.

Finally, there would be the speckled eye color alleles. Like heterochromia, I propose two alleles for variability: "Dominant Specs" and "Recessive Specs". "Dominant Specs" would be the dominant eye color with recessive specs, and "Recessive Specs" would be the recessive eye color with dominant specs. 

So the dominance order would be Normal Eye Color > More Melanin > Less Melanin > Mixed Eye Color > Dominant Heterochromia > Recessive Heterochromia > Dominant Specs > Recessive Specs

I might make concept art soon, so if you have any ideas for how you think these alleles should look in the genotype, lemme know!

Here are posts that these alleles were inspired by:
