Due to ectobiology, are all the kids related to each other or is there a disticnt split like, john, jade, jane,and jake are from the harley side and rose, dave, roxy, and dirk are from lolande and strider side?

John and Jade are genetically related (and to Jake and Jane), Dave and Rose are genetically related (And to Dirk and Roxy). No one else is. Roxy, Dirk, Jane and Jake were all clones of themselves, with no relation, with John and Jade coming from the mixing of Jane and Jake’s genes, and Rose and Dave from the mixing of Roxy and Dirk’s genes.
