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 molecular evolution, a haplogroup (from the Greek: á¼ÏÎ»Î¿ÏÏ, haplous, haploÃ»s, onefold, single simple And-Proto-Proto : *germanic, kruppaz round, mass) lump is similar haplotypes that share a common ancestor having the same single nucleotide (POLYMORPHISM) snp mutation in all. haplotypesaplogroups can be used to define genetic populations and are often geographically oriented. For example, the following are common divisions for mtDNA haplogroups: 1  African: L0, L1, L2, L3, L4, L5, L6. 2  West Eurasian: H, T, U, V, X, K, I, J, W (all listed West Eurasian haplogroups are derived from macro-haplogroup N).
