1. Sexual vs. Asexual Reproduction

2. How do Sexual and Asexual Reproduction compare?
DNA transfer through sexual reproduction (meiosis) and asexual reproduction (mitosis) equip organisms in different ways for survival.
Sexual reproduction: offspring receive chromosomes from two parents.
Asexual reproduction: a single parent cell divides into two new cells.

3. Mitosis & Meiosis 
Meiosis is the sexual reproduction that is being made
Meiosis = is the process by which the number of chromosomes is reduced by half as sex cells form.
Mitosis is the asexual reproduction
Mitosis = during this process the cell’s nucleus divides into two new nuclei and one set of DNA is distributed into each daughter cell.

New cells not genetically identical to parent cell
Two daughter cells
Chromosomes duplicate before cell division starts
Used in sexual reproduction
Used in asexual reproduction
Mitosis
Meiosis
Used for reproduction
Cell division occurs twice
Cell division occurs twice
Crossing over may take place
New cells have the same number of chromosomes as parent cell
New cells have half the number of chromosomes as a parent cell
No crossing over takes place

6. Sexual Reproduction
Sexual reproduction is the combining of an egg and sperm.
Results in offspring with a combination of physical traits from both parents
This is good for variation in genes.
Most mammals, birds, and fish reproduce sexually.

7. Asexual Reproduction
One parent produces a new organism identical to itself.
Has an exact copy of parent’s DNA
Takes place relatively quickly compared to sexual reproduction
Ex: bacteria, some plants, and some invertebrates (animals) like sponges, jellyfish, and worms

10. Comparing Asexual and Sexual Reproduction- Advantages and Disadvantages
Name some advantages of sexual reproduction
What characteristics would an organism have that would make sexual reproduction more beneficial for that organism?
Name some advantages of asexual reproduction
What characteristics would an organism have that would make asexual reproduction more beneficial for that organism?
For sexual reproduction-organisms are typically multicellular and able to move.
Advantages would be better genetic diversity allowing for better chances for adaptation.
For asexual reproduction-organisms are typically unicellular and smaller (many microscopic) and many also unable to move freely (sessile).
Advantages would be no need to find a mate and reproduction at a faster rate than in sexual reproduction.
