How to prove out genes

[t_h_wyman]

I will point you here quick:

Do real super leopards exist?

Breed animals with each gene together to get the two-gene combo. Take the two-gene combo and breed it out. If you only get both forms of each single gene but never the two-gene combo or an animal with neither gene, then you have an allele. Like if you breed a BluEL Lesser/Mojave, you only get Lessers and Mojaves, never more BluELs or wild-types . . . The one here is probably the most up-to-date as we aim to keep it so

@reptilian_rapscallions

these two genes I have named gravel and asphalt may be allelic, but I’m not sure

As both are proven allelic to YB then it is guaranteed they are alleles of one another. Further, Asphalt and Gravel have been proven to be allelic via breeding like above
