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.
Haplogroup 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.aplogroup R1b1 (M343, P25) (Western Europeans).
