aren't all fuchsias related, seeing as there can only be two alive at a time, therefore the gene that gives them the bloodcolor being fairly standard across bloodlines? even despite the other trolls mixing in. or is it some sort of genetic mutation that leads to a fuchsia being born?

Okay, All trolls are basically related since everyone’s juices just get mixed together. When I talk about trolls being related I mean like majority of genetic material, ancestor/descendant level related.
