1. Types of Reproduction Asexual Sexual

2. Background…. Heredity-The transmission of genetic information (through DNA) from parents to offspring Genetics- The science of heredity, dealing with resemblances (likeness) and differences of related organisms.

3. Purpose of Reproduction Why do organisms reproduce? To make sure a species can continue. Definition: Reproduction is the process by which an organism produces others of its same kind. (OFFSPRING)

4. Asexual Reproduction A new organism (sometimes more than one) is produced from one organism. The offspring will have genetic material uniform with the genetic material of the parent organism. This means they will be genetically alike.

5. Types of Asexual Reproduction Budding Regeneration Fission (Binary fission)

6. Budding Duplicate plant or animal begins to form at the side of the parent and enlarges until an individual is created. Very common in plants

9. Regeneration The ability to restore a full organism lost or damaged tissues, organs or limbs. (Common feature in invertebrates, like worms and starfish.)

12. Fission Also called binary fission. -Becoming two by division of the complete organism. A type of cell division.

15. Sexual Reproduction Requires two sex cells – egg and sperm -Found in humans and larger mammals The egg and sperm join to form an entirely new organism –Different from the parent organism BUT having genetic information from both parents

16. IMPORTANT TO KNOW! Asexual reproduction results in offspring that are genetically identical to the parent organism (exactly the same) Sexual reproduction results in offspring that are genetically different from the parent organisms (like characteristics). -This allows for DIVERSITY

18. DAY 2….Genes, Dominance, and Inheritance

19. Mendel ' s Theory of Inheritance The focus of genetic research shifted to understanding what really happens in the transmission of hereditary traits from parents to children.

27. CLONING THE FACTS…. Cloning in biology is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. The possibility of human cloning, raised when Scottish scientists at the Roslin Institute created the much-celebrated sheep "Dolly“. 1996-2003 Now on display in Scotland

28. Writing Assignment Write a FULL response to the following question If scientists were able to clone Dolly, they could soon want to clone humans. What are your views on cloning? What could cloning mean for the future? In your response include- Medical Advantages & Disadvantages Ethical Concerns (is this right or wrong & why) Possible Problems
