You state that Harry’s mother, Princess Diana, softened the creepy royal genes and now hers (Meghan’s) should help pretty them up a bit more. Perhaps. However, there is a chance that Meghan’s maternal genes (from her mum Doria Ragland) will be predominant. The wee one, upon arrival, may stand out from the crowd of other royal offspring.

Sparkle Markle's genes isn't going to "pretty up" anything at all! Perhaps muddy things up some, though, since she's got more of a mixed up genetic pool than anyone else in the Royal House members do.

The House of Windsor is mostly Germanic with some ancient Brit ( which include Norman French, Germanic [ Angles & Saxons ], and Celt )thrown in.
