Redemption line ternates are F1 ternates from two wc ternates that have specific looks that work well together to create a pattern structure that will help with aztec functionality.
Creating a phenotype that has back diamonds that arent too close together and some distance between them will help reduce striping on aztecs. It will take some selective breeding to get the US aztec production on the same level as overseas aztec production but its doable.
One or two breedings is all it should take to remove most of the mainland rounded connected back pattern structure thats causing the striping.
