Wild Roan/ Wild Type

[librarian]

Is the any connection between a swirling roan pattern and the Agouti Wild Type allele?

 

[Lucky_P]

E+ form of the MC1R gene that yields 'wild type' coloration is on chromosome 18
Form of the KIT gene that codes for roan is on chromosome 5

Do they influence one another... I have no idea...

I was learning about brindle perhaps being an expression of an E gene masked in red or red gene carrying cattle that could show up in a mating to an E carrier ( Braunvieh, for instance)
But I had once seen a "wild roan" shorthorn that was brindle marked, only in purple roan and white. So, I was just wondering if there could be a Wild Type gene interacting to cause that weird coloration..
Mysterious.
