Use this chart to determine the relationship, if any, of the gliders you plan to breed. Look at their lineage charts and find the closest common ancestor. Write it under "Common Ancestor", then add each name until you get to you glider. Do this for one glider across the top, then the second glider down the side. Where you two gliders' names meet (going across and down) is their relationship. Use the color chart descriptions to determine if they can safely be paired together for breeding.
