In the DNA of germ cells detected methyl modifications that remain in place even in the complete erasure other such modifications. Probably, these methylation-resistant foci responsible for the distribution of epigenetic code offspring.It is known that stress, smoking, endured disease, famine impose on our DNA its mark. Imprint literally: we are talking about epigenetic modifications, when the sequence of the DNA is the same, and the activity of genes can change radically. (In fairness it should be noted that such modifications may occur not only at the DNA, but also to the histones - proteins Read more [...]
Thus attempted to determine the effect of white and brown sugar on the fertility of the offspring in the second generation. The first offspring of both types of sugar about equally increased the number of newborn rats, but their average weight at day 30 in the group with white sugar decreased by 10 g, and in the group with a yellow rose 5 g compared with the control (Table 13) .

Experimentally, a violation of behavioral responses in the offspring of rats given large doses of pentobarbital (35-52 mg / kg) in drinking water during pregnancy. For example, these rats were increased research activity along with a decrease in the duration of the fixed period in a dark cell [Chapman J. W., Cutler M. G., 1982]. Similar results were obtained in rats high doses (200-400 mg / kg) Glutethimide (syn. noksiron) on 14-15th day of pregnancy.
