Question

Twenty years ago a small herd of horses was abandoned in the Pryor Mountains, Montana. The original herd consisted of one palomino paint stallion, one sorrel stallion, four sorrel mares, one palomino mare and one sorrel paint mare. These horses remain completely isolated, and they interbreed. Today the herd has grown to 90 animals.

a) the E/e (black/red) locus?

b) the C/Ccr (color dilution) locus?

c) the To/to (paint) locus?
