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.aternal 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.
