Cells in your stomach cells produce the digestive enzyme called pepsin. Cells in your bones do not produce pepsin. How does this specialization occur? Stomach cells contain a recombinant DNA so that this protein can be created Bone do not produce DNA, but stomach cells do. O Stomach cells contain different genes than bone cells O Bone cells express different genes than stomach cells

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
