Small mutations in the DNA causing small changes that usually are not physically apparent in identical twins.
PS: Do your own homework.
******Actually chemman being the daughter of a twin and having read up I can tell you that, yes you're right, but so am I. The DNA in identical twins is not 100% identical. There are small changes here and there. DNA lives to mutate.

The changes brought upon by the environment, even when they both, have the same genretical mapping.
Some traits in the phenotype , minor ones, such as hair style, skin color, and the degrees of color in the eyes, are normal variations, even in minor differences in social character and sociability, brought upon by the influence of surrounding ENVIRONMENT, (phenotype) despite the genoma is identical in both.
Phenotype, os not a 100% espresssion or our genetic makeup...

Also things that depend on individual development, such as finger prints.
