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.
It is a haploid gene â meaning that it has onlyâ one dose of chromosomes. The haploid mitochondrial DNA shows only the female lineage of a person. Diploid genes are two sets of combined chromosomes, the female set coming from the egg, the male chromosomes from the sperm. Mitochondrial DNA (mtDNA) is categorized into several types and groups termed haplotypes and haplogroups.
