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). DNA is found in the nucleoid.

11. Asexual Reproduction

12. Other Examples of Asexual Reproduction

13. Types of asexual reproduction

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

15. 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. Creating offspring with unique combinations of characteristics.

16. 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.

17. 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.

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

19. One Cell Makes Four Cells

What is the purpose of Meiosis?
What is our general description of Meiosis?
Make Sex Cells

21. 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

23. Sexual Reproduction

24. Sexual Reproduction key words
zygote: is a fertilized eukaryotic cell that has received genetic information from two gamete cells (sperm cell and an egg cell) to form a new individual.
gametes: cells from each parent that combine to form a zygote. Male gametes are called sperm. Female gametes are called eggs.
chromosomes: a DNA molecule that carries all of the hereditary information in the form of genes.
genes: basic unit and function of heredity. Act as instructions to make molecules called proteins.
Traits: inherited characteristics from parents.
