In which case Lyanna can't be providing any genetic material that will let Dany hatch/ride a dragon seeing as she has none herself as House Stark has never married a Velaryon or Targaryen and therefore nothing could have ever been passed down to her.
I've got a crackpot theory that Alysanne may have left more than just a dragon egg during her trip up north.
The World of Ice and Fire - The North: Winterfell
We can dismiss Mushroom's claim in his Testimony that the dragon Vermax left a clutch of eggs somewhere in the depths of Winterfell's crypts, where the waters of the hot springs run close to the walls, while his rider treated with Cregan Stark at the start of the Dance of the Dragons. As Archmaester Gyldayn notes in his fragmentary history, there is no record that Vermax ever laid so much as a single egg, suggesting the dragon was male. The belief that dragons could change sex at need is erroneous, according to Maester Anson's Truth, rooted in a misunderstanding of the esoteric metaphor that Barth preferred when discussing the higher mysteries.
We know that Barth is quite correct regarding the genderless nature of dragons, therefore Mushroom's claim seems quite reliable. Also, he seems rather like a proto-Tyrion.
I think Martin is teasing (oh so subtly) that Alysanne may have conceived or given birth to an illegitimate child at the Queen's crown tower while up north.
