we know that a genetic code transfer from one generation to another then i wan to ask is there anythng like that ke i person also trasfer its life time event memores to its offspring if yes then is it possible to see the past from this genetic coding

Yes and no. There are epigenomic differences in DNA methylation and histone modification/binding between individuals. These sometimes can be affected by environmental factors. In humans and other mammals, this information is typically reset in the germ line cells. However, there are a very small set of examples where these changes are passed on through the germ line cells. When this epigenomic information is passed on across individuals, it becomes "epigenetic."

 

Other species, most notably plants, actually reinforce the methylation status in germline cells. Most of our examples of true epigenetics is found in plants. One must be very careful, however, in interpreting this data in both animals and plants, because many epigenomic differences are actually caused by genetic variation and are known as "obligate epialleles." Those variants that are not dependent upon genetic variation are called "pure epialleles", of which only a handful are actually known and confirmed. There is another class called "facilitative epialleles" that is sort of a hybrid of the two and really difficult to define/classify, so I wont go into the details.
