I changed some of the gene symbols for certain traits in the kits' genotypes below, here are my thoughts on that:
- Bimetal is silver + sunshine, as opposed to golden/widebanding, so I changed the gene symbol from "Wd" to "sh". It's also likely a recessive trait (and possibly somewhat polygenic), so I just designed the kits as if your cat was sh/sh and mine was Sh/sh!
- I changed white spotting "S" to "Ws", just because it's what I'm more used to lol.
- I usually roll a die to decide which traits pass on to each kit, but for the Manx gene, I changed any kit that rolled M/M to M/m, because the Manx gene is considered lethal when homozygous.
- I learned that topaz is polygenic— it originated as a mix of two different dominant blue eye genes! DBE(alt) and DBE(cel), although I believe it now mainly uses DBE(alt). The actual inheritance patterns that I've seen in my brief research didn't follow a clear only-dominant or only-recessive pattern, so for the purposes of this breeding I treated it as a simplified incomplete dominant polygene. I also made a little visual diagram on topaz white progression in one of the layers— I learned that topaz very often causes cats to have white back paws and tail-tip, which is interesting!
