1. Asexual vs Sexual Reproduction

2. Phenomenon: Some lizards will lose their tails to escape their predators. Later they grow them. back

3. Asexual Reproduction
the creation of genetically identical offspring from a single parent.
Advantage:
No mate needed
Rapidly reproduce
All offspring identical

4. Asexual Reproduction
Disadvantage:
No genetic diversity!

5. produces two daughter cells genetically identical to parent cell.
Binary Fission
produces two daughter cells
genetically identical to parent cell.
Separation of body into 2 new cells
parent cell
DNA
duplicates

occurs in prokaryotes

6. Regeneration When an offspring grows from a piece of it’s parent
Sea Stars, sea urchins & planarians
Also can produce new body parts

7. Fragmentation An organism fragments into smaller pieces
Each piece forms a new organism identical to parent

8. Budding Budding: an offspring grows out of the body of the parent
The bud, when large enough, can break off of the parent and live on its own
offspring

10. Requires 2 parents Advantage: Male & female (egg & sperm)
Sexual Reproduction
Requires 2 parents
Male & female (egg & sperm)
Advantage:
Offspring are different from parents
Creates lots of genetic diversity
Helps with evolution-variation improves chances that species will adapt & survive
