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 R-M173 is a Y-chromosome DNA haplogroup, a subgroup of haplogroup R, associated with the M173 mutation. It is dominated in modern populations by two Eurasian clades, R-M240 and R-M343, which together are found all over Eurasia except in Southeast Asia and East Asia.ook-up mtDNA Haplogroup H at Wiki: In human mitochondrial genetics, Haplogroup H is a human mitochondrial DNA (mtDNA) haplogroup that likely originated in Southwest Asia 20,000-25,000 YBP. Haplogroup H is a descendant of haplogroup HV.
