Although identical twins share the same DNA, they don’t look identical cell-for-cell, because not every aspect of your physical appearance is rigidly determined by your genes. Fingerprints are formed semi-randomly as the foetus develops in the womb andare affected by such things as chance fluctuations of hormone levels. Similarly, the pattern of freckles and moles on the skin is caused by random mutations and will vary between identical twins.
It is due to differences in the mechanical forces each developing fetus experiences in the uterus as its cells proliferate.Even twins that develop from one zygote occupy different positions in the womb, and the variations are enough to make a difference .Identical twins have a very high correlation of loops, whorls and ridges.But “the detailed ‘minutiae’ , where skin ridges meet, end or bifurcate are different even between identical twins.”
