Definition: Asexual Reproduction

Definition: Asexual Reproduction. A single parent passes genetic information to the offspring which will produce an exact genetic copy. Asexual strategy example 1. Example: Binary fission Description: The parent organism divides into two separate organisms called daughters.

  1. Definition: Asexual Reproduction A single parent passes genetic information to the offspring which will produce an exact genetic copy.

  2. Asexual strategy example 1 • Example: Binary fission • Description: The parent organism divides into two separate organisms called daughters. • Type of organism: Bacteria (Kingdom Monera)

  3. Asexual strategy example 2 • Example: Budding • Description: A cell “bud” grows on the parent organisms. It develops on the parent then breaks off. • Type of organism: Hydra (Kingdom: Animal) Lives in the ocean

  4. Asexual strategy example 3 • Example: Spore production (Sporogenesis) • Description: Spores are formed through mitosis and dispersed like seeds. (NOTE: There are other ways spores are formed.) • Type of organism: mushrooms (Kingdom: Fungi)

  5. Asexual strategy example 4 • Example: Fragmentation • Description: A new organism grows and fully develops from a piece or fragment of the parent. • Type of organism: Segmented worms (Kingdom: Animal)

  6. Sexual Reproduction • Definition- Two parents produce offspring that have genetic characteristics from both parents. • By means of Fertilization: • Definition: Fertilization- The combining of male (sperm) and female (egg) to produce a zygote that has half the DNA of each parent.

  7. Two Types of Fertilization • 1. External Fertilization “Spawning” • Eggs are layed in water and male releases sperm near them. • Type of organism: Salamanders and Newts • Type: Fish • Type: Frogs and Toads

  8. 2. Internal FertilizationDescription: Eggs are fertilized inside of the female’s reproductive tract. • Type of organism: Snakes • Type of organism: Mammals (Whales, kangaroos, humans) Birth live young • Type of organism: Birds lay eggs after fertilization
