2. Asexual Reproduction
• A one-parent organism produces offspring
without meiosis and fertilization
• Offspring inherit the parent DNA
• Genetically identical
4. Fission
• Prokaryotes divide rapidly through fission
– Pro = No (no nucleus)
• Steps
1. The DNA molecule is copied
2. Each copy attaches to the cell membrane
3. Cell grows and splits
4. Finally, two new cells with one copy of the
DNA
*Original cell no longer exists
9. Animal Regeneration
• Offspring grow from a piece of the parent
• When the parent is cut or divided, the
pieces has the potential to grow into a
new organism
10. Regeneration
• “Regeneration” also means the ability to
grow back parts of the body
• This is not asexual reproduction because
it goes not produce a new organism
12. Cloning
• Asexual reproduction done in a
laboratory to produce identical
individuals from a cell or a cluster of cells
taken from a multicellular organism
13. Cloning - Plants
• Grown from meristems in culture
• “Meristem” – stem cells
14. Cloning - Animals
• All the clone’s chromosomes come from
one parent
• The first mammal cloned was a sheep
named Dolly
• Could save endangered species
• Ethical issues
