•the intentional breeding of plants and animals

•The ability to be physically active. A person is physically fit if he or she can pass tests designed to measure physical performance.

• generation

• fitness

• the manipulation of genes to fight or prevent diseases.

• it introduces a good gene into a person who has a disease caused by a bad gene.

• gene therapy

• genetic variation

•the branch of agriculture concerned with animals that are raised for meat, fiber, milk, eggs, or other products.

It includes day-to-day care, selective breeding and the raising of livestock.

• artificial selction

• animal husbandry

-All of the people born and living at about the same time

-A period of about 20–⁠30 years, during which children are born and grow up, become adults, and begin to have children

• generation

• grouping

•both cause changes in animals and plants.

•The difference between the two is that Natural Selection happens naturally, but Artificial Selection (selective breeding) happens only occurs when humans intervene.

• Natural Vs Artificial Selection

• Genetic Variation
