The Re: study says that the 72 year old man carries the eve gene to all British ancestors.
mtDNA is more reflective of genetic
in human genetics. In human genetics, the most widely studied haploid group is human Y chromosome deoxyribonucleic acid double group (YDNA) and human mitochondrial deoxyribonucleic acid (mtDNA), these two can be used to define the genetic population. The Y chromosome deoxyribonucleic acid haploid group is only inherited from the paternal line, while mtDNA is only inherited from the maternal line.
except for male sperm cells, there are mitochondria in all cells in the human body, but only the female mitochondrial genes can be inherited from their eggs. And men's mitochondria only accompany this man's life, and then end, can not be passed on to the offspring. MtDNA is a maternal inheritance. The structural type of mtDNA is an important index reflecting maternal context.
mothers contribute 50% of their genes to children and have the same influence on their genetic characteristics as fathers. In ancient times, polygamy sometimes robbed and defeated the national women as wives and concubines. As the victorious ethnic group does not adapt to the climatic and geographical conditions of the defeated areas (such as the Huaxi people who are not adapted to the cold, dry, frozen soil of the Hu people in the north of the North), the victorious soldiers are usually returned to their ancestral nationality with the concubines who have been robbed, and they live together to have their children. Children born to different wives and concubines, though half of the alien genes, are regarded as the people of their fathers in culture. When his son grew up, he continued to go to the alien territories to rob his wife and concubines. The grandchildren of their grandchildren had 75% different ethnic lineages, but they were still regarded as belonging to their grandfathers. Although grandson's Y chromosome is still the same type as grandfather, its maternal mitochondrial mtDNA and body autosomes are quite different from those of their grandfathers. Such a continuous cycle leads to the national culture and language, although it is still ancestral. Therefore, the structure type and proportion of maternal mitochondrial mtDNA in a national and regional population can reflect their heredity and ancestry characteristics better than the paternal Y chromosome.
Chennai probably never imagined that he was the grandfather of England.
the parents of chennaid are not black.
Ian Kinnaird, who paid 200 pounds to find his ancestors through DNA, unexpectedly found himself the oldest "grandfather" of all British people. The DNA results showed that the 72 year old man in Scotland had a unique genetic marker - L1B1, which traced back to the ancient African gene, the oldest woman discovered by human - Eve.
for the first time in Western Europe, the gene
a multinational research group was named "the British DNA" project (the project was to collect all the British DNA, thus establishing a complete "British Genealogy"), and was responsible for the DNA test of chennaid. The team leader said the DNA test results clearly showed that chennaid was "Eve's grandson", in other words, the 72 year old Scotland retiree was a direct descendant of the first woman "Eve" on the earth 190 million years ago.
members of the research group said that the old man in the little village near John Grosz, the north of the UK, had a unique genetic marker - L1B1, a sign that traced to ancient African ancestry and had never been found in any of the Western Europeans.
the number of mutations in the gene is 100 times less
> it is reported that genre's 30 thousand - year - old mitochondrial genome (mtDNA) is inherited from his mother, and the strange thing is that it had only two genetic mutations. The researchers say that most people inherit at least 200 times from their ancestors. The study also showed that chennaid, from his father's human Y haploid group (YDNA), showed that his hereditary composition was the same as the Scandinavia people, and that he had 1/4 of the Norway lineage.
chennaid learned the result and said: "before that, I have been living a modest life. Then suddenly, I became the ancestor of all. But I didn't feel honored, but I felt embarrassed. The researchers told me that my genes suggested that I was probably the offspring of slaves from West Africa to Britain. In 1959, I was studying the Bachelor of geography degree in Africa at Hull City University, but I never thought there would be such a link today.
is Senegal their hometown?
professor Aristall Moffat of the history of University of St Andrews and James Wilson, Professor of genetics of the University of Edinburgh, jointly established the DNA's multinational research group, which together examined the DNA results of chennaid.
Moffat told reporters: "this is indeed a surprising result, which means that he has indeed stayed in the garden of Eden. In addition, this result further proves that the British are descendants of "black Eve". This lineage was once found in Senegal, Africa, but never been found in such a lineage in northwest Europe. Those who have this lineage should be slaves sent to Liverpool. "
Wilson added, "maybe Eve and Adam exist. Eve, the mother of all of us, lived 190 million years ago, and then began to evolve as a homo sapiens. Of course, there were other women living like Eve, but only Eve's mtDNA stayed. Adam also lived in Central Africa, but he only appeared 140 thousand years ago. And only his YDNA is on the earth. "
but chennaid can't inherit his mtDNA, but his 56 year old sister can, and his daughter can continue to inherit this unique gene, but no one can ensure that other genes have new genetic mutations except chennade. Xiao Fan is translated from the Daily Mail
