In a DNA-hybridization study, DNA was isolated from wheat, labeled with 32P, and sheared into small fragments . Hybridizations between these labeled fragments and denatured DNA from different plant species were then compared. The following table gives the percentages of labeled wheat DNA that hybridized to DNA molecules of wheat, corn, radish, and cabbage. What do these results indicate about the evolutionary differences among these plants? Species                     Percentage of wheat DNA hybridized relative to wheat Wheat                          100 Cabbage                        23 Corn                              63 Radish                          30

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.
