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.
A second specific meaning of the term haplotype: a set of (several) single-nucleotide polymorphisms (SNPs, snips)âalso known as DNA sequence variations at specific nucleotide sites, or as polymorphic sitesâon a single chromatid of a chromosome pair that are associated statistically.he term ' haplogroup ' refers to the SNP/ unique-event polymorphism (UEP) mutations that represent the clade to which a collection of particular human haplotypes belong. (Clade here refers to a set of people sharing a common ancestor.).
