- EDIT: read pinned comment for a correction re: non-agouti amber cats. It seems they do eventually turn "ginger," it just takes longer & has the described "silver"-esque stage in the middle. The commenter DM'd me & provided this source: www.barnedroem.de/infos_amber...
Wanna know the genotype for a silver shaded cat or a golden chinchilla cat? Well this video won't tell you! Everything is confusing! Hahaha!!

Heyyy I have a correction about amber for you
Selfs don't become silver tabbies, they have pheomelanin. It just takes longer for it to show since their body is kinda "whittling down" at the eumelanin. They're basically the same as tabby ambers, they just have extra black pigment & take longer-their stripes especially linger for extra long, but later in life they will look golden/ginger 'cept for their leathers.
Can I get a source for this? :O
@@littlehungrywarrioryoutube may have deleted my reply for having links :T not sure if you could see it
@@frickfrickkin1723 oh jeez I hate when it does that. Is there a way to DM on youtube..?
@@littlehungrywarrior Welp it deleted it on multiple attempts so I will try messaging your tumblr if that's alright!
Good thinking!@@frickfrickkin1723
My brain is fried. I thought I understood cat genetics, but this lot has always stumped me.
mood.
This video is what I think about when dog people make fun of cats for not having proper breeds (I don’t know why they think this)
its just that dog breeds are generally more distinctive than cat breeds are. mainly because dogs have been domesticated for much longer than cats have, and also because dog breeds historically have been bred for specific purposes so their behaviour and morphology are more distinct to fit those purposes. But you're right, people don't give cats enough credit for how phenotypically diverse they are!
I just got some really awful news today and then this got posted and it’s making me feel just a little bit better to watch it. Thank you ❤
Aw ;v; I hope things get well for you soon, friend
YESSSS! I love thes videos I was really exited for this one! Cat genetics are fun but can be confusing, and I really like how you explain it.
Gime the knolege for my kitty oc's lol.
AHHH this series has been INCREDIBLY helpful (and started a new hyperfixation) in teaching me abt genetics and it's inspiring me to really put my creativity to use with a new project. thank you!!! (also i cannot wait for moreeee)
Me carefully looking over my cats to point out their phenotypes
At first i thought one of them was some sort of tortie but after looking up carnelian im having a revelation
I got a few moments of understanding about this topic while reading the genetics part on messybeast, but I forgot it very quickly. Thanks for making it as digestible as possible!
Why go to college when you can watch this series? This is amazing, thank you so much! (Offtopic, you should cover the bi-metal kitty)
Aw thanks! Bi-metal kitty? :O
I love cat genetics, and these videos help me learn even more about it!
YES I CAN HAVE A GOLDEN CAT CREAM GRAY TORTIE HERE I COME
Thank you! I have been so lost on widebanding research.
isn't there the sunshine gene as well that does similar things? from what I remember, this is the definition:
a recessive trait (appears in siberians) that's like golden but can also combine with silver/inhibitor to create something called "bimetallic." it's still being studied and is theorized to be on the extension gene.
Someone told me about that recently! Very cool :D
"boss battle music" oh no.
The inhibitor is completely dominant for the complete video. But in reality it could be incomplete with minimal difference between I/I and I/i.
Wideband: Makes the bands on tabby's large. It doesn't affect solid color cats. Wideband is a lot like spotting. Not a lot is known of wideband, but it is not monogenetic.
Wideband/Inhibitor interaction: Yeah I see why I chose Microbiology.
Extension locus: Modifier of Agouti.
E, e, r, ec
E > e & r
E = ec (?)
E > e ? r ? ec
E > r ? e ? ec
E = ec ? r ? e
I & Wb = Same as red genetics in e (unknown for r)
I & Wb = Carnelian (????)
[Another good reminder to stick to Microbiology]
Okay, punnet time.
Aa, II x aa ii
100% Inhibitor (50% Solid Inhibitor, 50% Tabby Inhibitor)
50% solid, 50% tabby
Im Cat lover i like visit you channel,.,,...
Thank god I took coffee this morning and notes as I am watching your videos or else my brain would become melted ice cream
hey, that's doing better than me! I MADE the video and it still turned my brain into melted ice cream LOL
@@littlehungrywarrior Sorry 😂
Wow!
Question, if a ginger is always expressing the tabby gene, but doesn't have the dominant "A" agouti locus on, would that cat be able or unable to express widebanding?
The cat can still express widebanding :) Google "cameo cat" or "red chinchilla," they look really cool!
I completely understand where this question comes from. Widebanding is a "modifier" of A, so shouldn't a cat with no As not have any available to modify?
The answer is very complicated & requires a deeper understanding of genetics, so forgive me if I have a hard time explaining.
It's shorthand to say that Widebanding "modifies" A. In reality (though still somewhat simplified), Widebanding alleles modify what A /codes for/.
"A" is the symbol we use to summarize & refer to the piece of DNA that codes for "make agouti banding," and "a" is the symbol we use to summarize & refer to the piece of DNA that codes for "DON'T make agouti banding."
Ginger removes A and a from the equation entirely. It doesn't matter if a is saying not to, ginger is going to make agouti anyway.
We say "Widebanding modifies A" bc Widebanding modifies AGOUTI, and A causes Agouti.
Imagine your friend is a sculptor and you're a painter. Your friend makes a sculpture and leaves it on your table. You come in later and paint it. The sculpture is agouti, and you're painting widebanding onto it.
If you come in and there's no sculpture, then you have nothing to paint (a/a on a black cat)
One day you come in and there's a sculpture, so you paint it. You have no way of knowing your friend didn't make that sculpture - someone else did (a/a on a ginger cat).
Of course this is all still simplified, but I think this kind of explanation will probably be more helpful to your understanding than like...a bunch of jargon about melanin-switching code lol
@@littlehungrywarrior Thank you for explaining! It makes a lot of sense now! 😊
Is there some form of genetic thing for eye color change cause I had a black cat whose eyes slowly changed from a brown to light amber over time not due to blindness or anything vets said they don’t know what happened
Not that I know of! :O Neat!!
1:58 question: why are there tabby stripes on these cats if they are solids/self cats. Are they added by the inhibitor?
It's added by inhibitor, yes :) inhibitor + solid cat = smoke, which is the ghost stripe pattern you see in the video.
I'm not sure why! sadly the mechanics behind a lot of cat colors is understudied :(
Do you know what happens if a self cat has inhibitor but not widebanding? Is a self and inhibitor cat always smoke?
yep, a self cat with inhibitor is always a smoke. adding widebanding would make them other stuff.
@@littlehungrywarrior What would widebanding make them?
@@3chovine have you watched the video?
@@littlehungrywarrior Yes. Sorry just rewatched and found it. Got lost on the tipped/chinchilla needing tabby as well.
I'm used to seeing Wb+Inhibitor+self=smoke. My preconceived notions got in my way. Sorry to waste your time.
Uh... save point. 10:55
Nigerian Forest Cat 😂 🇳🇪 🇳🇬
( 3:30 ) me: *Sees misspell* .... WHY!? AM I A MAGNET TO MISSPELLS??? WHY DO I KEEP SEEING THEM!! ... They are everywhere (I legit see misspells everywhere... even in high quality books!) (Warrior graphic novels, Chapter books, Ect)
are you referring to "torbie" as opposed to "tortie"? torbie is the word for a tortie tabby lol it's not a typo. if you see smth in the captions tho pls lemme now so i can fix it!
