1. Asexual Reproduction Look Ma! No Pa!

2. Asexual Reproduction Reproduction of organisms by mitosis
• Only one parent required • Process is very quick • Offspring are clones - genetically identical
• High risk of population collapse
Fission
Budding
Spores
Grafting
Cloning 

3. Fission Organism splits into two equal sized offspring
Protist (Paramecium caudatum)
Common in single celled organisms (like bacteria and protists; the nucleus replicates first then the cytoplasm divides through cytokinesis.

4. Fission - Sea Anemone
Sea anemones are multi-celled organisms that commonly reproduce through fission to form dense colonies of clones

6. Budding (Hydra sp.) Offspring starts as a growth (bud) on the parent
When old enough to survive on its own, bud detaches from parent
Bud
Mouth
Tentacles
Foot

7. Spores
Spore cells produced by parent that are specialized for reproduction
Each spore contains a nucleus and some cytoplasm
Spore will develop into a new organism if it likes where it lands

8. Grafting
Part of a plant is attached to the root system of another plant
The two unite to form a new plant containing the roots of one and the stem and leaf structure of the other.

9. Cloning
Clones are genetically identical to to the parent (a twin), except younger
Clones have the same genes as the parent, but environmental factors affect how they are expressed.
E.g. “Copy Cat”

10. Dolly – 1st Cloned Mammal, 1997

11. Cloning - Stem Cells
Unspecialized cells that have the ability to reproduce itself and differentiate into a specialized cell
Found in bone marrow, blood of umbilical cord, embryos etc.
