Not at all verona, I'm glad you did, that's how I found the forum.
I have been studying horse color genetics for a lot of years to figure out how to get the best color results from my breeding program. I had a grandson/great grandson of YELLOW MOUNT who was a red dun overo and homozygous for dun, but I was consistently getting red dun colts when I wanted the duns and grullas. Then when I started studying the color genetics, I got a bunch of bay, brown and black mares to breed to him and here come the duns and grullas! Another thing people need to look at is what bloodline mares cross best to their stud, in my case it was my KING bred mares.
Another problem that I have seen over and over is that people think that a horse can only be one color, especially all the people breeding to my "multi-colored" studs (I now have a palomino/dun overo, a dun and a silver blue grulla). A case in point is a guy who bred a Blue Roan granddaughter of Blue Valentine to my Palomino/Dun Overo stud RockyMountn Starburst
. He kept calling me back, totally confused, that he just couldn't figure out what color the filly was. Well she was a smokey buckskin/grulla/roan. She was black base color from her mama, smokey buckskin (dilution gene) from her sire, grulla (dun gene) from her sire, and roan gene from her mama. The only gene she didn't get was the overo-paint gene, what a picture she would have made if she had that one too!!
I currently have a web site with my horses for sale and studs on it if people would like to go see it: www.lastgoroundfoundationhorses.com
. I have posted at the bottom of each stud's page a bunch of pictures of their offspring so people can see what color each stud is throwing. I am currently working on a "Dun Factor" page to post on my site too. It has lots of pictures of dun factored horses, showing people the different colors and shades of red dun, dun, grulla, and also combinations such as palomino/dun (dunalino), buckskin/dun (dunskin), smokey buckskin/grulla, grulla/roan, etc. I am also posting a series of pictures that has the color changes of dun factored horses at different ages (ex: babies to weanling to yearlings etc), to show people what color these dun factored babies are born and what color they change to, especially the dramatic changes in the grullas! Hope this helps people. P J
