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, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. These haplogroups have led some researchers to trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread across the globe.
