DNA Tests are Uncovering the True Prevalence of Incest

[70sEraVet]

25. I was thinking, as i was reading the article, that there is another type of incest...

that wouldn't show up in the dna data banks as an incestuous relationship. A child produced by a stepfather wouldnt carry the tell-tale dna signature of incest that the people in the article are dealing with. Yet it is still incest, and so that is yet another portion of an unknown quantity added to the percentages.
And, as was pointed out in the article, this is ONLY talking about those incestuous relations that resulted in an offspring that grew to maturity. Hardly a measure of all incestuous relationships.
The emotional damage that has been done must be on an astronomical scale.
(My wife, a survivor of incest, often SCREAMS in her sleep. I hate to think about how many others do that, or how many others found tragic ways to escape from the pain)
