DNA is analyzed to determine evolutionary relationships, study populations, identify individuals, and diagnose genetic disorders.
The natural world consists of a diversity of organisms that transmit their characteristics to future generations. Living things reproduce, develop, and transmit traits, and theories of evolution explain the unity and diversity of species found on Earth. Knowledge of genetics, reproduction, and development is applied to improve agriculture and human health.
The development of technology has allowed us to apply our knowledge of genetics, reproduction, development and evolution to meet human needs and wants.
