1. What’s the difference in these two forms of reproduction?

2. White boards:
How does sexual and asexual reproduction affect the passing of traits to offspring?

4. For this unit, we will look at reproduction with a more specific focus on the passing of traits.

5. Reproduction Sexual Asexual vs.
Specific kingdoms will be discussed in the classification unit
Sexual

6. Asexual
Reproduction

7. Asexual Reproduction
Most unicellular organisms, and a few multicellular organisms use cell division to reproduce in a process called asexual reproduction.
A parent organism produces one or more new organisms that are identical to the parent and live independently of the parent
Specific kingdoms will be covered in the Classification Unit

8. Asexual Reproduction
The organism that produces the new organism or organism is the parent
Each new organism is an offspring
The offspring produced by asexual reproduction are genetically identical to the parent.

9. Asexual Reproduction

10. Asexual Reproduction
Binary Fission is a form of asexual reproduction that occurs in cells that do not contain a nucleus (Prokaryotes)

11. Asexual Reproduction

12. Other Examples of Asexual Reproduction

13. Sexual Reproduction
Specific kingdoms will be covered in the Classification Unit

14. Sexual Reproduction
Type of reproduction in which two parent cells (male and female reproductive cells) combine to form offspring with genetic material from both cells.

15. Heredity is the passing of Genes from parents to offspring.
A Eukaryotic cell has a Nucleus that contains genetic material.
Heredity is the passing of Genes from parents to offspring.
A Gene is a section of DNA that provides instructions for specific traits.

16. A Chromosome is the structure that holds the genetic material (DNA).
DNA is the genetic material that provides instructions for all the body’s functions.
Review slide about the location of the genetic material from the previous lesson

17. Sexual Reproduction
Each species of living things has a characteristic number of chromosomes.
Humans have 23 pairs, for a total of 46 chromosomes.

18. One Cell Makes Four Cells
Sexual Reproduction
What is the purpose of Meiosis?
What is our general description of Meiosis?
Make Sex Cells
One Cell Makes Four Cells

19. Sexual Reproduction
The process of Meiosis creates sex cells (sperm and egg in humans) that contain half the genetic material (half the 46 chromosomes)
During sexual reproduction, sex cells are combined to form unique offspring.
46 Chromosomes
23 Chromosomes
