Sable Chin is an agouti <A_B_cchl_D_E_>
Smoke Pearl Chinchilla is <A_B_cchl_ddE_>
Smoke Pearl is a self <aaB_cchl_ddE_>
If he is a sable chin, that means he's got one copy of the sable allele, as does the doe. Any kit that gets both copies of <cchl> will be a seal (or seal agouti). It's not a sure thing, especially since lionhead litters are usually small, and color prediction is a statistical thing, but it's reasonably likely. If he is sable chin, you will probably also get himi or REW, since those are the only alleles that sable chins and smoke pearls can carry at the second C locus. Also, you will not get
any chinchilla or full-color kits out of sable x smoke pearl.
If he is
not sable chin but rather chinchilla, at least some of the bunnies will probably be chinchilla, due to his chin <cchd> overpowering the doe's <cchl>. (I don't think you're going to get any full-color kits because the doe can't make them and he seems to be lacking any tan, so he's almost surely either chin or sable.) You may
still get seal chins if he just happens to carry sable in the second position at the C-locus, or you may get sable chins if he carries himi <ch> or REW <c>.
If he's a smoke pearl chinchilla, both he and the doe are dilutes, so the entire litter will be dilute colors. So you'll get some combination of blue seals (probably some agouti), smoke pearls (again probably some agouti), blue himis and/or REW.
Other colors depend on what he and/or the doe carry in the second position at the A, B, and E loci. You may get self seals or sables rather than chins, chocolate versions of the varieties, pointed colors or sable frosties.
I'm inclined to think he's sable chin due to the sprinkling of ticking and the brownish hue to his color, but he
could be blue seal agouti (which is a tricky color to identify since it tends to look like a slightly off-colored blue or dark smoke pearl, and he obviously has very litte color to go on). If he is a blue seal agouti, you will get
only dilute seals and sables (or pointed or frosty versions of those), since all the kits will get a sable allele from him, and they will get either a sable, himi or REW allele from the doe, depending on what she carries in the second place at the C locus.

Clear as mud?
But fun!
