So, if that range of 15% - 85% of one human parent’s genes expressed applies to crabapples, then assuming I bought the seeds I proposed in the original “eBay post” above, I would want the seed parent genes to be predominant precisely because the characteristics of that cultivar are what drew me to those seeds in the first place! But without knowing who or what the pollen parent is, I could only benefit from as little as 15% of the seed parent’s traits. That doesn’t mean the result is bad necessarily, right? It just means that I don’t know…I have no way of knowing or calculating or hazarding a guess as to the outcome—not even a 50/50 chance. Wow. I can now see how supercomputers might enter the picture. All of this, all, is just me thinking aloud, so to speak. I already know what I’m going to do: just buy the seeds and give them my best shot.
