Dale, I'm not hostile to the point you're trying to make. The other curators could tell you that I'm a great fan of woo-woo. I own a metaphysical bookstore, and I'm the head of the trade association for the New Age industry.
You can guess that I have some experience juggling science and mysticism. It's just my personal opinion, but I don't think it helps anyone to confuse the two.
You clearly find extraordinary personal meaning in the fact that members of your immediate family look like various royals from hundreds of years ago. You feel a mystical connection to them. Fine. But, it won't work, I don't think, to ignore the science or jumble the science in an effort to make science prove something it doesn't prove.
By your own account, your genetic inheritance from the Tudors is tiny. In fact, it's so small that you are struggling against overwhelming odds that you have any genetic link to the Tudors at all, except perhaps for your y-DNA.
As far as anyone can tell, given the current state of the science, the y-chromosome is mostly junk that doesn't do anything. And, even if it turns out that maybe it's not really junk, the science shows that it has nothing to do with physical appearance. The y-chromosome determines maleness, and probably does some other stuff with the hormones.
Science also tells us that all of human appearance is determined by DNA. New research into epigenetics suggests that the genetics might be a little more complicated than we thought 10 years ago. But no one has yet suggested that being descended from kings overrides the other rules of genetic inheritance.
So, it seems to me that you're painting yourself into a non-rational corner. Human appearance is determined by DNA, but you have very little Tudor DNA (if any). The end of it is that science does not support your idea that your relatives look like royalty because you're descended from the Tudors.
I don't happen to agree that there is something mystically magical about the blood of kings. A bunch of thieves and thugs, if you ask me. But, you disagree, and that's fine. My point is something else -- if there is something magical about the blood of kings, science hasn't discovered it. Personal opinions on the subject are just personal opinions.
We can look forward to new discoveries in the field of genetics, and we can dream that scientists might someday discover that royal ancestry plays by different rules. More likely, I think, they'll discover that there is something that says some genes related to physical appearance cluster together over the generations. Maybe certain patterns resist random recombination. Maybe recombination tends to to "repair" a pattern by only combining with other genes that support the pattern. Who knows? Could be anything.
Until then, it doesn't work to try to prove a Tudor descent using DNA if you have to ignore the accepted rules in order to make the proof look plausible. In the end, it doesn't prove anything. Speaking from experience, I would say that as soon as you try to bend science to support mysticism, you're on tricky ground.
