I have been working on spotted red angus based on a Corriente cow , Red Angus bull combination. The Red Angus has recessive genes for
color and so far have removed the horns on crosses in the first generation. It can be a crapshoot for color as you can get all black, all red to
brindle to red and white (also black and white) spotted. There is also a 50 % chance of a bull calf and another delay in genetic progression.
I would think one would need to use a bull with recessive genes for color in any case to take advantage of any color scheme you are shooting
for. So far I have made it as far as 7/8 red & white spotted. Any 15/16 thus far have been solid red. I do believe it possible to get both red
and white or black and white 15/16 but it will require a foundation Red Angus (not built up from cross breeding) The goal is a spotted calf from
a Red Angus and 15/16 spotted heifer cross. Temperment will be a subject for another discussion.........
