So I always thought that the agouti gene restricted the expression of black and had no effect at all on red (ee) horses. Then I came across this website which claims that the type of agouti gene the red horse carries is responsible for the different shades of red expressed.
The first half of the page (difference between classic bay, wild bay, and brown) seems to be correct based on what I've read elsewhere, but then the bottom half of the page explains how those different agouti genes modify red horses. Can any of our color experts on here confirm whether or not this is true?
Any owners of red horses who have had them tested for agouti care to share their results?
I know there's a lot of misinformation out there on the 'net, but I'm surprised to find a website that seems to have correct information about the different types of agouti alleles followed by incorrect information about how they affect red horses.
