- Genetic Engineering.
- The process of manually adding new DNA to an organism.
- The goal is to add one or more new traits that are not already found in that organisms.
- Genetic engineering: Advantage: genetic engineering, most of the diseases and illnesses can easily be prevented through isolating the exact gene that causes them.
- Genetic engineering: Disadvantage: it can pose potential health risks.

- natural selection: organisms That are better adapted to their environment tend to survive longer and transmit more of their genetic characteristics to succeeding generations than do those that are less well adapted.
- Selective breeding
- Selective breeding or artificial selection is when humans breed plants and animals for particular genetic characteristics.
- steps taken for selective breeding
- Deciding which characteristics are important enough to select.
- Choosing parents that show these characteristics from a mixed population.
- Breeding these parents together.
- Choosing the best offspring with the desired characteristics to produce the next generation.
- Repeating the process continuously over many generations, until all offspring show the desired characteristics.

- prokaryotes (bacteria, blue-green algae)
- Protoctits
- Kingdom, phylum, class, order, family, genus, specie

- fungi moulds ,yeast,mushrooms.
