Do twins have the same finger prints?
No. fingerprints that can be readily distinguished on close examination. However, the prints do have striking similarities. In fact, before the arrival of modern genetic testing, similarity of fingerprints was often used to determine whether twins were identical or fraternal. Fingerprinting, along with other physical characteristics, is an example of a phenotype — meaning that it is determined by the interaction of an indivdual’s genes and the developmental environment in the uterus. The ultimate shape of fingerprints are believed to be influenced by environmental factors during pregnancy, like nutrition, blood pressure, position in the womb and the growth rate of the fingers at the end of the first trimester. Thus, you will find similar partterns of whorls and ridges in the fingerprints of identical twins. But there will also be differences — just as there are differences between the fingers on any individual’s hands.
