If Zan was messing around with one of his followers wife or girlfriend I bet they would not say:
Oh this is OK

I was part of a group that ran a study in a few counties in the UK doing DNA analysis on newborn children, for inherited genes, it was based around tracking certain hereditary conditions, whether they were passed more along the maternal or paternal gene lines. Quite interesting stuff.

The results did not match up, some things that should have been passed down the paternal line were missing from the children in some cases, these are conditions that ARE passed down, so it was odd that they were not. So a thorough investigation of the samples was started.

Anyway, one of the things that did come out of it was that around 32% of the children's DNA did not match that of the father who's DNA was given as the father. This ended up invalidating the study as it affected the results so much.

The samples were anonymised, ie no names or ages or stuff, but kept together in family groups (mother/father/child), at first we thought that some of the samples had been mixed up but it was such a percentage that there was doubt about that.

They re-ran the study a year later and came up with a similar figure then as well, after using much more rigourous conditions for collection and storage of samples.

Needless to say, that little result was not passed onto the parents. (or onto the authorities, though I believe that through other studies they are aware Pof it and have been for a LONG time)
. It has become a lot easier for this to happen nowadays that this practice is relaxed, but it has gone on all along.

Why exactly was this study not released to the authorities, let alone the public?

I'm sure it would cause quite an uproar.

Why do I feel you answered your own question...
