Selected examples of the ability to differentiate between catfish allelic variants and gene duplicates (paralogues) using both blue catfish and channel catfish sequences

The topological stability of the neighbor joining trees was evaluated by 1000 bootstrapping replications, and the bootstrapping values are indicated by numbers at the nodes. Channel catfish and blue catfish genes placed into the same clade indicate that the additional, related channel catfish sequence is likely a paralogue rather than an allelic variant
