The muscles of the foot, along with a tough, sinewy tissue known as the plantar fascia, provide secondary support to the foot. The foot has internal muscles that originate and insert in the foot and external muscles that begin in the lower leg and attach in various places on the bones of the foot.
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.NPs are locations on the DNA where one nucleotide has mutated or switched to a different nucleotide. Because a haplogroup consists of similar haplotypes, it is possible to predict a haplogroup from the haplotype.
Maternal haplogroups are of greatest interest if (a) they have a known history or (b) they enable people to discover others who are related to them. Scientists are continually revising the tree that indicates which mutations define each maternal haplogroup, and how all the haplogroups are related.The more up-to-date the tree used for haplogroup assignments is, the more accurate and more meaningful those assignments are.n general the higher resolution the haplogroup, the more meaningful the sharing of a haplogroup. For example, if your haplogroup is H2, you share that haplogroup with over 600 23andMe customers; on the other hand, if your assignment is H2a2b, you share that with just over 60 customers.
