Each human mitochondrion contains, on average, approximately 5 such mtDNA molecules, with the quantity ranging between 1 and 15. [6] Each human cell contains approximately 100 mitochondria, giving a total number of mtDNA molecules per human cell of approximately 500. [6]
The full genetic basis of hair color is complex and not fully understood. [1] Regulatory DNA is believed to be closely involved in pigmentation in humans in general, [2] and a 2011 study by Branicki et al. identified 13 DNA variations across 11 different genes that could be used to predict hair color.
This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. [5] Since animal mtDNA evolves faster than nuclear genetic markers, [6] [7] [8] it represents a mainstay of phylogenetics and evolutionary biology.
Each human cell contains approximately 100 mitochondria, giving a total number of mtDNA molecules per human cell of approximately 500. [35] However, the amount of mitochondria per cell also varies by cell type, and an egg cell can contain 100,000 mitochondria, corresponding to up to 1,500,000 copies of the mitochondrial genome (constituting up ...
The cells in the human body are not outnumbered 10 to 1 by microorganisms. The 10 to 1 ratio was an estimate made in 1972; current estimates put the ratio at either 3 to 1 or 1.3 to 1. [299] The total length of capillaries in the human body is not 100,000 km.
Phylogenetic tree of haplogroups I (left) and W (right). Kya in the left scale bar stands for thousand years ago. This phylogenetic tree of haplogroup W subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation [2] and subsequent published research.

The mtDNA control region is an area of the mitochondrial genome which is non-coding DNA. This region controls RNA and DNA synthesis. [1] It is the most polymorphic region of the human mtDNA genome, [2] with polymorphism concentrated in hypervariable regions. The average nucleotide diversity in these regions is 1.7%. [3]
