That's right. The sire being homozygous for black means he can only
pass on a black allele for the base color, and all red-based colors
(sorrel, palomino, red roan, etc) need to have received a red allele
from mom and dad instead of one black.
Your possibilities with that cross are black, smoky black (which
doesn't look any different from black), bay or buckskin. In fact, if
he's homozygous for bay, or if your mare is carrying a bay allele (bay
doesn't affect red pigment so you wouldn't know just from looking), you
might only be able to get bay or buckskin, no blacks.
take care,
cindi
