Humans and Neanderthals interbred — but it was mostly male Neanderthals and female humans who coupled up, study finds

This article says the lack of Neanderthal X chromosomes is relative and depends on mostly Neanderthal man marrying (or raping) Sapiens tribe women.
Rather, the surprisingly high amount of modern human DNA chunks found in Neanderthals can be explained by mate preference, the researchers concluded. Because females carry two X chromosomes and males carry only one, a preference for mating between female H. sapiens and male Neanderthals would mean fewer Neanderthal X chromosomes would enter the human gene pool, producing the pattern the researchers identified in the genomes.
That pattern being, half paragraph a little earlier:
There are regions on the X chromosome — the sex chromosome that every human has at least one copy of — where no living humans have any Neanderthal ancestry.
The problem with this solution is, if this were the reason, one would see Neanderthal Y-chromosomes more. Check this:

Comment expliquer la disparition du chromosome Y néandertalien ?
This suggests, but the other more recently published article denies, the solution of toxicity. Now, the article could be true in the main solution.
Neanderthal men could have raped or seduced sapiens women, but only their daughters survived pregnancy. Possible.
I still think there is another solution. And that it's preferrable.
No purebred Neanderthal man was on the Ark, and if any purebred Neanderthal woman was, the only candidate is Noah's wife, supposing her daughters in law were not her own daughters, whose mitochondriae didn't survive ... but actually, supposing there are so few Neanderthal X chromosomes, this would hardly be the case if every one of her three sons had one from her.
So, Noah's mother could have been Neanderthal, her mitochondriae cannot be passed on beyond him and her X chromosomes only to daughters, not to sons, of him.
Or any one of the daughters in law could have had a Neanderthal father. His Y chromosome was not passed on to and therefore not through a daughter, and the X chromosome he passed on would have been one out of two in her, then out of four more in the other inlaws, then the three sons would between them have inherited both X chromosomes from Noah's wife. So, overall 1/8.
Purebred Neanderthals (except possibly Noah's wife) were not on the Ark. The remainder of Neanderthal genomes are a selection of the selection of them that was on the Ark.
