As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent, usually dating back thousands of years.
As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual. An individual inherits his or her cytoplasm and the organelles contained by that cytoplasm exclusively from the maternal ovum egg cell ; sperm only pass on the chromosomal DNA, all mitochondria are digested in the oocyte.
When a mutation arises in a mtDNA molecule, the mutation is therefore passed in a direct female line of descent.
About the author
Mutations are copying mistakes in the DNA sequence. Single mistakes are called single nucleotide polymorphisms SNPs.
Descendent populations belonging to haplogroup M are found throughout East Africa, Asia, the Americas, and Melanesia, though almost none have been found in Europe. The N group may represent another migration out of Africa, heading northward instead of eastward.https://cuispacberdunc.tk

Shortly after the migration, the large R group split off from the N. Products of this store will be shipped directly from China to your country.
