If these issues have been studied in the human example, we would have to wait very long until the formed base of observations of several generations. In particular, a study of 30 generational change about 500 years it was necessary to spend any more. However, through the use of fruit flies, you can explore the hereditary transmission of the problem for 30 generations in just a single year.
