The videos you included in your hub are particularly interesting with respect to the subjects of obesity in the U.S. and also about Downs Syndrome. Good job! Thanks!
I believe that you are correct in that both are important but often the environment has a huge impact beyond physical characteristics or inherited genetic traits.
I believe you are correct. We cannot do much about the genetic makeup of what we have inherited except to be aware of certain risk factors & deal with them as best we can by lifestyle. As to environment, as adults we can work to make changes.
Thanks for writing a hub on this subject.
I have often thought it interesting the studies that have been done on identical twins separated at birth & reared apart...just how similar they are in the things that they choose to do & how they live.
