Top 10 Countries With DNA Matches (MyHeritage)

[Grace O'Malley]

Commercial DNA matches include X chromosome but not Y chromosome so results are not really relevant

They are as they are based on autosomal dna however people need to check surnames. With my results a lot of it is diaspora Irish but Irish are close to English populations also so there is some shared ancestry. In both the USA, Ireland and Britain I have real relatives due to actual ancestry from generations ago such as a brother of my grandfathers who went to UK and ancestors that went to US and these are verified. With Scandinavia they are all Scandinavians so possibly due to shared ancestry in Northwestern Europe. With the French result there are more Isles names cropping up but also some are French so similar shared ancestry. Some of the ones down further on my list are definitely mostly due to diaspora populations.

My point is they include both X chromosome and Autosomal without accounting for the Y chromosome so it doesn’t give the full picture of your relatives

In population genetics your X and Y is not a factor in your relationship to other populations. For example cousins can be a completely different ydna and not sure if by X you mean mtdna? But the same holds true. Ydna for example is good at looking at distant connections and the same with mtdna. Anyway both y and mtdna are not a factor in these lists as they are entirely based on autosomal dna and the same with plots showing which populations cluster with each other. So in the end y and mtdna are irrelevant in this.

FTDNA is the place for ydna and mtdna if you want to look into that further.

My brother's ydna uploaded to yfull. He is M222 so very Irish centric.

He's the one here marked in yellow. On FTDNA they go into a lot of detail and I know that ydna descends from the Northern Ui Neill. It is further down M222 (i.e. the so called Niall of the Nine Hostages marker).

I've also had the full mtdna sequencing done and that is also uploaded to yfull.

Mine is marked in yellow. Mtdna is more varied but all my full matches are Irish also.

This is from ftdna. I've got 3 exact matches in Ireland. The rest of the list is 1 step matches. As you can see mtdna is spread around more populations but relationships are more distant.



So while all is interesting to find out your closest relationships and relatives you need to use autosomal dna.

False. Y chromosome is 2% of your entire genome and you share that with others under the same haplogroup. 23&me uses mtdna for dna relatives so it is used for relationship to other populations and as a factor in these lists . The only explanation as to why they don’t use Y chromosome but use the X is because everyone would get millions of matches so they don’t put it. The 2 screenshots will explain it.

X-DNA and mtDNA are different:

The X-chromosome is included in autosomal DNA tests, but not all let you see matches from shared X-DNA specifically.

I give up. If you believe that then possibly someone else can explain better than I can.

I'm aware X chromosome is different than mtdna. It has more chromosomes than ydna for example but it isn't used to trace ancestry so I'm not sure what the relevance is here. Just looking at myself and my daughter she shares 49.8% dna with me and I share 50% with my mother (this is on MyHeritage), my brother shares 37.7% dna with me and a 2nd cousin shares 6.4% and a relative whose grandfather was my grandfather's brother shares 2.4% dna with myself. This is all from MyHeritage.

The man from Ethiopia is White (saw photo) with an Italian name.

The man from Ghana is White (saw photo) with a Scottish/English name.

The three from Japan have no photos but all have British names.
