I have pointed out several times now – Arabs have all the same Caucasian haplomarkers Europeans do, plus four more, making then Semitic White rather than Indo European Aryan White, that no other ethnic group has.It stands to reason that Europeans have some haplomarkers in common with Arabs.Carol Thatcher, Margaret Thatcher’s daughter has 24% Arab heritage: http://genealogy.about.com/b/2006/10/30/thatchers-middle-eastern-roots.htm

Look up the statistics on government aid in the US – the largest numbers, and, percentages, are Whites. GEE – China sure seems to be enjoying the interest on the loans the US gets from them. Seems the Japanese have made the most advancements in technology lately. Set aside your bigotry.

Guess you just don’t like Arab/Black admixture – that is how J* got there, or, any of the other ethnic groups – your source is OLD and OUTDATED – even used one of YOUR other source to show J* doe NOT occur in Blacks – NOW, consider it resolved – you need not respond further.

You can have the last uninformative word on J*12f2. This issue is resolved. Kaput. Dead. Done. Buried. I shall not respond to this topic again.

Get interesting.

“The Y chromosome provides a unique opportunity to study mutational processes within the human genome, decoupled from the confounding effects of interchromosomal recombination.

…It has been suggested that the increased density of certain dispersed repeats on the Y could account for the high frequency of causative microdeletions relative to single nucleotide mutations in infertile males.

…Previously we localised breakpoints of an AZFa microdeletion close to two highly homologous complete human endogenous retroviral sequences (HERV), separated by 700kb.

…Here we show, by sequencing across the breakpoint, that the microdeletion occurs in register within a highly homologous segment between the HERVs.

…Furthermore, we show that recurrent double crossovers have occurred between the HERVs, resulting in the loss of a 1.5kb insertion from one HERV, an event underlying the first ever Y chromosomal polymorphism described, the 12f2 deletion.

…This event produces a substantially longer segment of absolute homology and as such may result in increased predisposition to further intrachromosomal recombination.

…Intrachromosomal crosstalk between these two HERV sequences can thus result in either homogenising sequence conversion or a microdeletion causing male infertility.

…This represents a major subclass of AZFa deletions.

Resolved as in Arab admixture gives many Ethiopians, Somalis, and Sudanese more Caucasian looking features above, and, beyond phenotypical variation, and that the J* haplomarker group ia a Semitic White haplomarker occurring in Semites, and mixed peoples.

Resolved as in there is Arab admixture in Ethiopians, Somalis, and, Sudanese, that give them a more Caucasian look than phenotypical variation, and, the J* haplomarkers are Semitic White that are present in these groups.

FIRST, quit denying Arab admixture for the more Caucasian looks of Somalis,Ethiopians, and,, Sudanese, BEYOND phenotypical variation – even your OWN sources back this – it happened – get over it.

SECOND, read the article MORE closely -QUOTE,”“…The p12f2 PROBE(***emphasis, mine***) also detected Y-specific DNA fragments in the gorilla and chimpanzee.”” It was NOT detected but used to find fragments – translation – SIMILARITIES between apes,and, humans – chimpanzees vary genetically from humans by less than 1/2 of 1 %. Keep trying – how many times, NOW, have you told us this matter was resolved???

“…The p12f2 probe also detected Y-specific DNA fragments in the gorilla and chimpanzee.”

Are these also White-Semites?

You blew it. The deletion is a unique genomic evolutionary event.

You are wasting my time. This issue is resolved.
