As humans, we should cherish our connections; our relationships with family. This correlates with biological science. I owe the science of genetics for providing me with a family to love, especially when it comes to sisters! With similar personalities and physical features it all involves the intricate details with genes of a family, and how each member relates to another with slight variation. In fact, our DNA is 99 percent alike! With that, it allows me to communicate with my sisters and others with ease, share our natural environment, and feel safe while "bonding" with each other. Hey, maybe there is a little bit of chemistry involved too!
