I think my boy Lucifer is a black self with low white, but I'm not sure! He appears almost rusty red in sunlight with tabby stripes, and his black fur is white at the base as you can see on his arms in the first photo!

This lovely kitty looks like a black smoke with low white! What a gorgeous boy! His stripes are a result of ghost or phantom striping, where a cat is genetically solid but due to the smoke gene they appear striped.

It's kinda weird to me that the whole point of silver is inhibiting phaeomelanin, but it doesn't turn red cats gray or white like you'd think... but yet the agouti gene doesn't affect red at all... red is so weird lol

Cat's orange is certainly something very unique and not like anything else in other animals.

On the other hand, I strongly believe every interaction or phenotype can be explained if we understand the molecular processes behind the pigment production, the roles of the color genes and the changes brought by their mutations. These things aren't random even if we don't understand them yet.

Agouti probably doesn't affect red because the protein it codes (ASIP) regulates eumelanin production (switches it over to phaeomelanin), and in reds eumelanin is impossible to produce, so there's nothing to regulate. Thus no effect.

And why does inhibitor leave red stripes? Well, I don't know, the exact pathway is still unknown, but the known silver loci are in non-coding, gene regulating areas of the genom, so they are affecting the phenotype through other gene(s). Maybe it's some tabby pattern gene that's only active during the "background" bands' pigmentation! Or maybe the inhibitor effect is only so strong, and to more pigmented stripes keep enough phaeomelanin to visually remain red. Or maybe the phaeomelanin produced in different agouti bands is slightly different, so they react to inhibitor differently. I'm sure we'll get the explanation someday.

Australine was isolated from the seeds of the Australian tree Castanospermum australe (figure 19.17) and is also an inhibitor of glycoprocessing enzymes.

It’s also known as HVM-5. Known to enhance human abilities, but the first injection usually causes seizures, cardiac arrest and sometimes, death.

Do cats with wideband(not sunshine) and silver exist? ive been looking for examples for ages

Yeah! You've probably already seen some, just didn't realize it. As wide band makes the yellow agouti bands wider, and silver removes the pheomelanin from these bands, wideband+silver makes mostly white cats. Their names work the same as the golden series: silver tabby (this is a bit unfortunate, since low grade wide band silver is called the same as no wide band silver), silver shaded (tabby), silver tipped, silver shell, silver chinchilla.

Black silver shaded tabby, with brick-red nose leather and black toebeans, characteristic to all black tabbies. This is reveals that this is not a dominant white (W_) cat.

This 1cm fella seems to be a black smoke! What a pleasant fella!

The cat i made with this! Shes a chocolate silver lynx point with white!

go check the picrew out! it includes golden tabbies (which i dont see too often in cat genetics related content) and im excited to see everyone's kitties! Reblog with a kitty you made :3

HI... I've made another extremely self indulgent picrew

I made the majority of this in one night and polished it for another two days, this thing was built purely in a cat genetics autism fueled need to see if it was possible to make

it's not a perfect visual representation of all possible cat colours, there's only so much I can do within picrew's simple image layering, but I've done my best to make most colours look close to real life or at least nice looking

there's instructions included if you want to use it the way I built it to be used, but they're completely optional and you're welcome to just mess around with it with no rules if you prefer!

sending you tabby #164838, but can you please id this baby? we got her a week ago and her pattern is really interesting and different from tabbies i've owned before

showed this cat to a friend and she said "He's so silly hes think he is Dino :3" so everyone say 'thank you sydney' for her service in providing things for me to put into this post to make it look longer so people actually pause to linger on it and therefor instinctually believe that the post is somehow funnier for it's assumed self awareness, when it actually is attempting to be unfunny and their attempt at introspectiveness, and therefor like or reblog the post. everyone say 'thank you sydney'

on a first glance, black tabby, but then i used my eyes to actually look at the cat, and that's a black silver tabby! specific patterns i'm going between, because it could be broken mackerel OR broken braided. going w/ broken mackerel bc thats a kitten and it takes a bit to be sure.

hello! this might be a stupid question but if smoke makes the hair roots white then why do the hair tips also become white? like the black smoke pictures you've been using for the tournament.

All right, that's actually a very good question, and I'm not entirely sure I can fully answer it. (I've never had a longhaired smoke in my hand, so i can only speculate based on pictures.)

Cats have different kind of hairs: guard hairs, awn hairs, down hairs. In a smoke, the hairs making up the undercoat are much lighter than the rest, the standard black with white base 'upper' hairs. I don't know what kind of hairs the "mane" of a norwegian forest cat with its coat at the fullest consists, but i suspect it's different then those covering the back and the sides of the cat, and that's why the white is much more apparent there.
