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.
Haplogroup R1b, also known as haplogroup R-M343, is the most frequently occurring Y-chromosome haplogroup in Western Europe, as well as some parts of Russia (the Bashkir minority), Central Asia (e.g. Turkmenistan) and Central Africa (e.g. Chad and Cameroon).aplogroup R1b is in other words now identified by the presence of the single-nucleotide polymorphism (SNP) mutation M343, which was discovered in 2004. From 2002 to 2005, R1b was defined by the presence of the SNP named P25.
