Ok so I need a little help. I am looking for any information anybody has on "sooty" palominos I have read alot about the creme gene and dilutions on the chestnut and bay genes and understand the whole Palomino vs cemilo vs chestnut part but my issue is what EXACTLY makes a Palomino "SOOTY". I just bought a mare that has genetically tested as "sooty" palomino and so I am being lead to understand that it is some sort of genetic varaition and not just a darking of the palomino coloring.
I've done a lot of research on palominos since buying one!
The 'sooty' effect is a 'modifier' in the same way that the dilute gene causes the palomino effect on the chestnut. In the same way that the grey gene can vary a horse between very dark grey through to white, the sooty gene can cause anything from a few dapples through to giving the coat a 'dirty' look and some seriously heavy dappling. 'Sooty' palominos also have a tendancy to change colour with the seasons.
The sooty gene doesn't only work on palominos - it can cause variations in any coat colour, and it is thought that any form of dapples (apart from in greys) is caused by the sooty gene.
Dapples can come from the sooty gene or they can sometimes be cause by nutritional factors (fat horses). 99% of the time dapples cannot be seen in the winter coat. As for the "black spots", are you talking about something kinda like this?
