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.
As of May 2008, nearly 70% of the Y-DNA results submitted to the Ybase website were Haplogroup R1b, while only 17% were Haplogroup I and 7% were Haplogroup R1a. A 2005 study found that 58% of white American men are in Haplogroup R1b.aplogroup R1b1 (M343, P25) (Western Europeans). Most of the participants in the Cheek DNA study, including everyone in the main related groupswhat we've been calling Group 1 and Group 2 (see Results Summary)are in Haplogroup R1b1. This is the most common Y-DNA haplogroup in western Europe.
