Hey, so if you're like me and have a lot of trouble focusing/going through the lineages, this is super handy!

Just copy and paste both linages into the text box like this:
Be sure to add in the tokos you are breeding, just to make sure they don't show up on each other's lines.
Then check these results!
Ignore the sd/unknowns, or remove them when copy pasting, then check for any 2 or mores! If you don't find any, then you're good to go!
