I thought the NOVA documentary, “Ghost in Your Genes” was very interesting. This documentary stressed genetic differences between siblings, especially identical twins, and a genome and the role methyl tags play in that. Growing up, you learn and see that identical twins are identical in both their genotype and phenotype. However, I was surprised to know that even though twins contain the same genes they are determined by switched in our DNA. This switches, which are part of the epigenome, help to determine one’s cellular identity.
I found the study between the mice extremely interesting. The scientists were able to prove that our genes not only affect our genetic makeup and our physical appearance but also our personality! This study also stressed the importance of nature vs. nurture and how both play an important role in one’s personality. I find this phenomenon incredibly important and can see how it is proven true in almost all organisms world wide.
I also found the Sweden study of transgenerational effects extremely pertinent and think this point needs to be brought to attention more often. People need to learn to not be selfish with the poor choices of taking care of their body, such as smoking or binge drinking for their poor decisions can affect their future generations. Every person needs to be responsible for their own genome and take care of it. This responsibility needs to be taught to children and even adults. Our genome. Our responsibility.
