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

Asexual Reproduction Disadvantage: No genetic diversity!

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 cell begins to divide daughter cells occurs in prokaryotes

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

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

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

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
