The couple attributes these characteristicsto their intake of epigenetic supplements. Now theywish to have another child and have informed their physician thatthey intend to greatly increase the amount of supplements theytake to increase the epigenetic effects in their child. The physiciancautioned them that studies available in human trials showno effect of choline on learning and that excess intake of folateduring pregnancy may be associated with an increased risk ofautism spectrum disorder in the child.

For the assignment this week I want you to play this epigenetic game that will show you how your choices (which will be the equivalent of of external factors in someone life) make your genes act differently. Last week, we learned about biology and race and how these fit together in the formation of biological determinants and social misconceptions. For this week's discussion, play the game. Discuss with your classmates what happened, and what you have learned about epigenetics and how this changes your understanding of genetics . How do epigenetic changes and epigenetic mechanisms in general influence health, our concepts of race, and inequality?arrow_forwardExplain why Epigenetic Traits Are Heritable ?arrow_forward1) using at least one named example discuss the implication of allelic heterogeneity in single gene disorder for the presentation and progession of the disorder and its treatment 2) discuss the importance of understanding epigenetics in improving people healtharrow_forward
