Well, she's pretty... Hopefully she'll have pretty babies. What does the mare add to the equation in Appy color? In Paints, they give very little credit to the mare.
Dusty is the mother of Speed and of Little Bit (sold) both solid and both times bred to colored studs. But, both will roan out to look like her most likely.
Friday has one dominant LP gene (she has to have because of her color). So there is a 50-50 chance of her having a baby with color if bred to a solid stud, odds of course better with a stud with color. Tuffy has two LP genes, he will always throw color, no matter what he is bred to.
