What are you on about? How is using multi-gene animals with unknown lineage going to help ensure the OP gets nice Bees? The question was not how to get 4, 5 or 6 gene animals.
THIS is part of the thought process that floods the market with sub-par Bees. Many of the not-so-great Bees we see are cast offs from multi-gene breeding where the base ingredients were not well considered.
The best bet for producing solid spectacular bees is to pair the cleanest, brightest Spider with the absolute brightest Pastel that can be found. THIS is the building block that have the best chance of netting great results. THEN those offspring can be used to make spectacular 3 and 4 gene animals. Not the other way around.
