The distribution of Y-chromosomal single nucleotide polymorphism (SNP) haplogroups and short tandem repeat (STR) haplotypes was determined in a sample of 102 unrelated men of Arab origin from northwestern Algeria (Oran area). A total of nine different haplogroups were identified by a panel of 22 binary markers. The most common haplogroups observed in the Algerian population were E3b2 (45.1%) and J1 (22.5%). Y-STR typing by a 17-loci multiplex system allowed 93 haplotypes to be defined (88 were unique). Striking differences in the allele distribution and gene diversity of Y-STR markers between haplogroups could be found. In particular, intermediate alleles at locus DYS458 specifically characterized the haplotypes of individuals carrying haplogroup J1. All the intermediate alleles shared a common repeat sequence structure, supporting the hypothesis that the variant originated from a single mutational event.
I’ve been over at Dienekes and found this. I can’t access the full text 😦
- 22 J1 22.5%
- 8 E3a-M2 8.6%
- 6 E3b1-M78 6.12%
- 40 E3b2-M81 45.1%
- 5 J2f-M67 5.1%
- 1 R1-M173 1%
- 11 R1b3-M269 11.2%
- 1 Q-M242 1%
I noticed the R1’s there. It’s unlikely to be from Europeans, probably the ancient Y chr’s from the back migration from Eurasia, plus some variants of it. R1 is also seen in the Sudan, Cameroon and the Ouldeme, in surprisinly high amounts.
