Apart from we don't know (at least I think we don't know!) whether he is eeSgSgUU or eeSgSgUu - maybe Sue does know because she knows his pedigree!
Crossing a silver sable and a sable should give Het Silver Sables eeSgsgU*, sables eesgsgU* and possibly some creams eesgsguu if both parents were het for the umbrous gene.
Just to stretch my genetics muscles......crossing with his Auntie LBJ would be:
Sire: AaeeSgSgU* (we know he is Aa from his father)
Dam: aaEeSgSguu (we know she is Ee from her BEW parent)
So your possibles would be
(if sire homo for umbrous):
25% Umbrous Silver Grey AaEeSgSgUu
25% Umbrous LBJ? aaEeSgSgUu (not quite sure what that would be!)
50% Het Silver Sable AaeeSgSgUu and aaeeSgSgUu (not sure how the aa would affect it, assuming it would be cancelled by the ee?)
(if sire het for umbrous):
the above (halve the %s!) plus
12.5% Silver Greys AaEeSgSguu
12.5% LBJs aaEeSgSguu
25% BEWs AaeeSgSguu and aaeeSgSguu (again assuming ee cancels aa?)
Yes Hamsters in Focus is a good place to lurk to read about things like this
