Real G25: parent-child relationships

[rothaer]

In the meanwhile I invested into eleven G25 coords samples from my family and it's interesting to see in what way children can deviate from the parents and from each others. I show it here in the North Europe PCA. For orientation I added a few more individuals that have published their coords.

I deviate from my parents in a northeast direction, but you can see that this position of mine is "stable" as the children with wife2 are nicely in between her and me. Main deviations between them are just on the northeast-to-southwest cline. The same is seemingly true for the wife1 children. Wife1 is not tested, but I imagine that her position in the PCA could be determined with some confidence.

Actually I also seem to be in between my parents, just shifted along an imaginary northeast-to-southwest axis.

I wonder whether this is applicable also to other parent-child relationships in the North Europe PCA.

So if you have (real) G25 coords for parents and a child, feel free to display the results. Try to do it in the North Europe PCA, even if you happen to be somewhat outside the default dots.

Very cool. Do you have a comparison table in Vahaduo for eg, where their early Germanic-Keltic-Slavic proportions are compared?
Would be interesting to see how much they can vary.

Yeah, here in the G25 Feiichy ancient Slavic calculator 2.1 (contains your already mixed Balkanites Novo Selo and Velic) and seems less bouncing between Balkan and Graeco-Roman:

Thanks for posting! they vary quite a bit. :)

I've got my mother and myself. It's bizarre the way this has Scots as Germanic and Irish and Welsh as Celtic.

Mine doesn't make a whole lot of sense. I'm about as Northwestern as I could be from my parents dna, another sibling could potentially be to the Southeast of them. Might buy them a kit one of these black fridays.

K36 takes it to the other extreme.

Funny comparison.

And yes, thanks, your result does not support that northeast-southwest only shift from the average of the parent's results. But okay, still learning.

There was a similar thread over on Anthrogenica. My observations from that thread, and from generally looking at results over the years:

- People who's parents are from different ethnicities are split more evenly between parents in the modeling and plotting.

- People who's parents are from the same ethnicity are split less evenly between parents in the modeling and plotting. The children in same ethnicity families seem to plot randomly around the parents.

One big exception to this is gixajo, he gets modeled 50/50 between his parents (on G25), in spite of the family being the same ethnicity.

You got 8 kids, man?

Good job, I admire your endurance.

Anyways,

Yep, thanks.
The PCA looks graphically convincing.

Thanks for info.

The special gixajo conditions will be due to the well known priciple of the Spanish limpieze de sangre. ;)

But serious again. I guess it could be about magnifying the PCA if all three are close together. If you look at the PCA that eupator posted you will hardly be able to with the eye determine possible deviations from the exact mean of both parents. I don't know, but I guess if you determine the mean of both and then magnify the PCA the same way you would do for two parants from the same ethnicity, there could be the same "arbitrary" deviations in all directions.

Happened to have this graphic already from a comparison of simulated coordinates vs the real McCoy. Includes myself and parents on the PCA map you requested.

Was your mom on a trip to Paris 9 months before you were born?

Fortunately, everything is correct.

I have done another dna test. I must get the G25 to see how I plot with it
