What is J chromosome?

Haplogroup J-M304, also known as J, is a human Y-chromosome DNA haplogroup. It is believed to have evolved in Western Asia. The clade spread from there during the Neolithic, primarily into North Africa, the Horn of Africa, Socotra, the Caucasus, Europe, West Asia, Central Asia, South Asia, and Southeast Asia.

What is the difference between J1 and J2 haplogroup?

Of the two main sub-groups, J1 takes up four-fifths of the total and is spread widely on the continent while J2 is more localised around the Mediterranean, Greece, Italy/Sardinia and Spain. There is also limited evidence that the subclade J1 has long been present in Central Asia.

Where does J1 come from?

In fact the origins of J1 lie around the Caucasus, which explains that all branches other than P58 are most common in that region, as well as in Anatolia and Europe.

What is a halo group DNA?

A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, “onefold, simple” and English: Group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation.

Is there a separate mitochondrial haplogroup called J1?

For the completely separate and distinct mitochondrial haplogroup also named J1, see Haplogroup J (mtDNA).

What kind of disease is associated with Haplogroup J?

Within the field of medical genetics, certain polymorphisms specific to haplogroup J have been associated with Leber’s hereditary optic neuropathy. Around 45,000 years before present, a mutation took place in the DNA of a woman who lived in the Near East or Caucasus.

Where is basal haplogroup J found in the world?

Furthermore, inferring close associations between a haplogroup and a specific archaeological culture can be equally problematic. Basal haplogroup J* is found among the Soqotri (9.2%). Haplogroup J occurs in approximately 12% of native European populations.

Who was the King of England with Haplogroup J?

Richard III of England had J1c2c3 mtDNA haplogroup. in Bryan Sykes’ book The Seven Daughters of Eve, haplogroup J is referred to as ‘Clan Jasmine’.
