My dwarf orange female is matting with my dwarf brown male (he is carrying the orange gene). This SHOULD result in 75% orange and 25% brown offspring!
Actually, according to simple mendelian genetics (which is what I think we have here), you should be getting 50% pure orange crayfish and 50% brown crayfish that carry the orange gene.
In other words you have: Bo + oo = 25% Bo + 25% Bo + 25% oo + 25% oo
B=brown
o=orange
large letter = dominant trait
small letter = recessive trait
Either way, let's hope this mating results in eggs.

Keep us updated.
Thats correct. It is simple mendilian genetics in that case. However it is no dominant or recessive trait. Both colors show in the mixed type.

Hello all, sorry to intrude...
DanHagen. Nice pair of crays.
Do genetics always work this way with crays? Brown carrying recessive gene for orange never throws a BB when mated to orange? Do young always carry the recessive gene?
thanx, Sher

THe orange is not a recessive gene.

Thank you CanadianCray.
The orange is a 'trait', not a 'gene'.
I've learned something useful. Thanks!
