It appears that the two melanistic females on the left belong to the same breeding "pair" as the red and white male right between them. The ones to the left are also a separate breeding pair. The tribe seemingly only has four immunity genes (since its easier to juggle) - The Home Island Immunity, E, G, I.
No breeding goal has been fully reached, but I will make sure that the ones chosen as the next breeding pairs will all have Mega Horns so I can cross that off the list.
