Sexual vs Asexual Reproduction

• Only involves ONE parent

• Offspring are clones (Identical) to the parent

• The offspring has the same DNA as the parent

• Type of reproduction by which offspring arise from a single organism or one parent

• Produced via mitosis

• Offspring inherit genes/DNA from only 1 parent

• The offspring are genetically identical (clones) to the parent

Binary Fission

Binary Fission- is when 1 bacteria or simple organism splits into 2.

A fully grown parent cell splits into two halves, produced 2 identical cells

Only occurs in single celled organisms

Budding

• Offspring grows out of the body of a parent

• Offspring still identical to the parent

• Example is showing the budding of a hydra

Fragmentation

• Body of the parent breaks off

• Each piece can grow into a new FULL organism

• Tissue regrows due to regeneration

  • Regeneration is when a piece of a damaged organism can regrow

• Examples are Sea stars (starfish)

• Sexual reproduction involves offspring created from TWO parents.

• One parent produces male gametes and one parent produces female gametes.

• Gametes are produced during meiosis.

Pollination

Pollination is a form of sexual reproduction found in flowering plants.

Pollen (sperm cells ) will fertilized the ovary (egg cells) of flowers to produce new plants

Advantages of Asexual Reproduction

• Rapid population increase

• Only 1 parent- does not need to find a mate

• Fast and Energy Efficient

Disadvantages of Asexual Reproduction

• NO genetic diversity

• Species may only be able to live in 1 habitat

• Species MAY be more vulnerable to diseases and environmental changes

Advantages of Sexual Reproduction

Creates genetic diversity

Species MAY be more resistant to environmental changes

Species MAY be more resistant to new diseases

Disadvantages of Sexual Reproduction

Takes more time and energy to find a mate

Takes energy to make sex cells

Individuals who cannot find a mate end up NOT reproducing
