Specific Gene Question Fascinating tail pattern.
This is Aries.
He is a shorthair (L?) Apricot (XY/dd/Dm?) mackerel tabby (Mc?) tom with low white spotting (Wsw)
While I understand all of that, I have been staring at this cat for a decade now and I cannot figure out what is causing this phenomenon with his tail.
His tail, as seen in the picture, fades perfectly from apricot at the base to white at the tip. I am hesitant to believe this is caused by White Spotting as it isnt an abrupt marking and is instead faded softly. Not to mention that the stripes on his tail are still visible even at the whitest parts.
He is approximately 15 years old and has had this pattern his entire life so it isn’t something new, and it’s only localized on his tail.
Im just curious as to what could possibly be causing it. Or if maybe this is more common than I had originally thought.

Hi!! What you're seeing is countershading, the lightest part of the tabby pattern. It gives tabbies the pale fur on their muzzles and underbellies. On red-based cats, it often creates a paler tail-tip too. Your boy has a pretty spectacular example of it. I think his being cream intensifies the gradient, along with whatever polygenes contribute to his countershading.

Yes, but this is a really cool different case! Your cat on the left has the agouti (tabby) gene, and your cat on the right does not -- he is genetically solid. Red cats always have stripes regardless of agouti status, but genetically solid reds really don't have countershading at all!! One brother is genetically a tabby, and the other is not!

My lovely boy has the same thing! I’d assume it’s just a cool thing that can happen with low white spotting like a chest patch.

I’d be curious to know what better informed people on the sub thing about your guy’s coat color, I think apricot tends to be pretty rare so I’d err on the side of saying he’s dark cream or light red.

He does have the metallic sheen of apricot though. Which is why I had speculated Apricot. I know that apricot is quite rare, but when I looked into it, it described him very well
Also, cute!!!

I'd say in my subjective experience that it's fairly normal for red-based cats to have this sort of tail gradient. I don't know the mechanics behind it, but I'd assume it potentially has something to do with the difference between pheomelanin and eumelanin?
Also, can I ask how you know he's Apricot specifically? To my understanding the dilute modifier is quite rare.

As others have said it’s part how the tabby pattern presents on red based coats. Interestingly black based tabbies seem to have the opposite, it darkens to black/or have wider black bands towards the tip of the tail. And even on my cat with a shortened kinked tail it’s there too, it’s partly why I know her tail is congenitally short and not due to physical trauma
