Without diversity and variation among humans, the world would be quite monotonous. Although these disparities materialize on the exterior (e.g. hair color, eye color, widow’s peak, etc.) the authentic distinction lies deep within one’s genome. A genome consists of an organism’s DNA, thus providing the blueprint for growth and development (Moalem, 2014). Well-known physician, scientist, and author, Sharon Moalem expounded on the significance of genetics in one of his most prominent novels, Inheritance: How Genes Change Our Lives and Our Lives Change Our Genes. A myriad of biological concepts exist in this novel, all of which relate to genetics and the laws of inheritance. A few of these topics include: how genes are regulated/expressed, how a single change in DNA can alter the protein it codes for, and how ethics has an effect on genetics. These topics pertain to Big Idea 3: Living systems store, retrieve, transmit, and respond to information essential to life processes (CollegeBoard, 2015). Contrary to Mendel’s famed notions - the idea that the fate of one’s genes is mapped out with some DNA coming from the mother and some from the father - Moalem demonstrates that although one’s genome may be set in stone from day one, the way one expresses those genes may differ completely (Moalem, 2014). Learning objective 3.15 corresponds to what was previously discussed: Mendel’s laws deviate from the inheritance of traits. As expressed in the learning curriculum, transcription
