Some organisms reproduce sexually involving two parents. Sexual reproduction results in offspring that have greater genetic diversity than those resulting from asexual reproduction. One-half of the offspring’s genetic information comes from the “male” parent and one-half comes from the “female” parent. These genetic differences help to ensure the survival of offspring in varied environments.
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.
Organisms reproduce, develop, have predictable life cycles, and pass on heritable traits to their offspring.
