I have had this input from ~T~ who i know from another forum, he's bred and keeps lots of hybrids and some amazing looking fish.
Anyway, he has given me his input on my Jellybeans and kindly permitted me to post it here
They are short bodied convicts (jellybeans) but this is a genetic defect not because of breeding to a parrot. So your fish are actually pure so to speak (the same way both a fancy goldfish and regular goldfish could be called pure). The pink gene is unique to the pink convict and cannot be transferred to other cichlids. I know this because I have bred both a pink con to a parrot and a short body con(jellybean)to a parrot and the offspring are not only not pink but look nothing like jellybeans. They will cross with sajicas though, I have also had this pairing.
~T~ has a Blood Parrot forum that i am a member of if anyone's interested
