Presentation Transcript

  1. Asexual Reproduction Genetics & Heredity

  2. Asexual Reproduction + - No genetic variation – same DNA Can outgrow environment • Same DNA • Requires one parent • Rapid

  3. Binary Fission • Simplest form of reproduction • Parent reproduces genetic material • Divides into two daughter cells • Examples • Bacteria • Protozoa • Some Algae

  4. Budding • New organism develops from an outgrowth or bud • Examples • Hydra • Yeast • Sponges

  5. Spores • Specialized cells with tough outer coating which protects inner cell • Examples • Ferns • Mushrooms • Fungi - Mold

  6. Regeneration • Ability to re-grow lost body parts • Some organisms can grow whole new organism from a single piece of the original • Examples • Sea stars, star fish • Salamander • Gecko

  7. Vegetative Propagation • Cells separated from parent to form completely new independent individual • Examples • Roots • Stems • Runners • Cuttings • Other structures: tubers, corms, bulbs

  8. Cloning •  Scientifically engineered, genetically identical copies of a biological entity • Examples • Naturally occurring - Identical Twins • Dolly • Body parts
