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.
In human genetics, Haplogroup R-M173 is a Y-chromosome DNA haplogroup, a subgroup of haplogroup R, associated with the M173 mutation. It is dominated in modern populations by two Eurasian clades, R-M240 and R-M343, which together are found all over Eurasia except in Southeast Asia and East Asia.ook-up mtDNA Haplogroup H at Wiki: In human mitochondrial genetics, Haplogroup H is a human mitochondrial DNA (mtDNA) haplogroup that likely originated in Southwest Asia 20,000-25,000 YBP. Haplogroup H is a descendant of haplogroup HV.
