70 trillion genetic combinations
Doodling with my 4 months old baby photo... and she becomes twins... The DNA carried so many genetic data, human kind has 70 trillion genetic combinations, resulting in differences in appearance and other things that will ensure no two beings could be exactly the same. Not all genetic information is used in the forming of a human body. Only about 5-10 % of active genes seen as phenotypes, the rest are 'sleeping genes' or genotypes that do not appear as phenotypes, the so-called dormant. Dormant genes are present in our DNA as about 90-95 % of the entire genes. Recent research states that these genes are not exactly sleeping, but they regulate other functions essential to the stability of the DNA itself. There are more dormant genes than that appear as phenotypes. All genetic information is stored in DNA in the form of very thin ribbon inside our body cells.
