I too would like your explanation of a double recessive gene. As Chuck has stated, both the jag and spider ball are co-dom traits that have either a lethal super or one that has not been produced yet. The theory is that the spider also has a lethal white super and hence why none have been produced.
And just FYI, we do have olives here. If you are interested in some, I can direct you in the right direction.
