Haplogroup U3b

Hello and welcome to my Blog. Here I will write about my Genealogy and Gentic's.

Mt dna haplogroup U3 is found at low levels throughout Europe, the Near East and Central Asia. U3 is present at higher levels among populations in the Caucasus (about 6%) and among Lithuanian Romany, Polish Romany and Spanish Romany population. There are two subclades U3a and U3b. U3b is found in the Romany population of Europe about 55% of  Romanies are U3b.

My Mitochondrial dna haplogroup is U3b, I know this because I had my Mitochondrial dna test, with Familytree DNA, in 2010.  A week or so later I received an e-mail from Familytree DNA  which stated, I also have an exciting opportunity to include my mitochondrial DNA results in the research of their Chief mtDNA Advisor, Dr. Doron Behar. Dr. Behar is an internationally renowned researcher and my participation will help him find new insights into our shared heritage. Dr. Behar not only works with the National Geographic Genographic Project but has also authored many journal articles about mitochondrial DNA. Past research topics have included the women of Africa, women of Jewish ancestry, and the modern Druze population. I contributed  my results, by replying to the  e-mail. And have not heard anything since!

About a year after receiving my Mtdna results, I decided to have an autosomal  test. At the time Familytree DNA had not started their Family Finder test, so I decided to have the autosomal test with 23&me. I wanted to connect with cousins that I had not find whilst I was researching my familytree on and I had not made one connection with my Mitochondrial dna results.

Having received my autosomes results from 23& me I sent my raw data to Dr Mcdonald for analysis. He confirmed that I have Asian genomes and that I have South Asian on my X chromosome. My sister tested with 23&me she also has South Asian on the Xchromosome in the same place where mine is.

My mum passed away several years ago so the nearest I was going to get to my mums genomes was by having her sister (my maternal aunty) tested.  I asked my  aunty to have a  DNA test with 23&me. She consented to have a test.  My aunty who is in her late 70s and has Diabetes found it hard when doing her sample, it took at least half an hour for her to complete it. I was dreading it, if she had not done the sample properly she would of had to repeat it, but has luck goes she did not have to repeat the test. About four weeks later, her results came back from the lab, (even thou they were my aunty's results I felt as if they were my mums)  I  then sent her raw data to Dr Mcdonald. I received her results from Dr Mcdonald a day later. She also shows on the Ancestry Painting that Dr Mcdonald had sent me, on the X chromosome South Asian in the same place has my sister and myself. I  sent my aunty’s raw data to Harappa Ancestry Project here are her result.

South Asian 10%
Onge 3%
East Asian 1%
SW Asian 19%
European 64%
Siberian 1%
Papuan 1%
San/Pygmy 1%

PloS ONE: Reconstructing the Indian Origin and Dispersal of the European Roma: A Maternal Genetic Perspective.....Is an article about the Maternal line's of Roma from a gentic perspective. I found the article very interesting, hope you do too. 

I sent an e-mail to David Comas one of the Authors, asking him about haplogroups Paternal H1a and Maternal U3b. Here is his reply.
Thanks for your message.
Haplogroups H1 and U3 are lineages that are quite frequent in India and very rare in Europe. Their frequency in Roma is relevant as a result of an Indian origin of Roma. However, at this stage it is difficult to say more than this.

I am finding it very hard to believe that U3 is not of Indian origins. And believe there has not been enough samples tested to say other wise.
