Originally agenda was the plural of agendum, meaning a thing to be done. However, it became applied to a list of things to be done and in this, the most usual modern sense, it has become firmly singular with the plural agendas. Compare with Data.
A haplogroup is a genetic population group of people who share a common ancestor on the patrilineal or matrilineal line. Haplogroups are assigned letters of the alphabet, and refinements consist of additional number and letter combinations.ecause a haplogroup consists of similar haplotypes, it is possible to predict a haplogroup from the haplotype. A SNP test is required to confirm the haplogroup prediction. Not all the testing companies offer SNP testing, and consequently their customers' haplogroup predictions are sometimes inaccurate.
In human genetics, Haplogroup I-M170 is a Y-chromosome DNA haplogroup, a subgroup of haplogroup IJ, itself a derivative of Haplogroup IJK. Y-DNA Haplogroup I-M170 is predominantly a European haplogroup and it is considered as the only native European Haplogroup.-chromosome analysis had suggested Paleolithic ancestry among populations in the Iberian Peninsula and that Iberia may have played a role in the re-population of western Europe after the last glaciation.
