3. How many cells are produced as a result of meiosis?
• 4

4. Explain what occurs to
• Chromosome number splits in half the number of chromosomes in the resulting cells.

5. Identify the types of cells produced as a result of meiosis.
• Gametes
• Sex cells (sperm and egg)

6. Identify the location of meiosis in males and females.
• Gonads

7. Describe • Genes get shuffled around what • Results in daughter cells occurs to the genes not being identical to each in a cell other.
undergoing meiosis.

8.
Describe 3 differences between mitosis and meiosis.

• Mitosis
- Asexual
- Same # of chromosomes as the parent cell
- One division
- Used to reproduce body cells (somatic cells)
• Meiosis
- Sexual
- Half the # of chromosomes as parent cell
- Two divisions
- Used to produce gametes (sex cells)

Let ’ s summarize…
1. Describe the two types of cells that our bodies consist of.
2. Explain the difference between asexual and sexual reproduction.
3. Explain the difference between mitosis and meiosis.

D
E
1. What process is represented in the diagram?
2. Describe the genetic makeup of daughter cells.
3. What does phase A represent? What occurs in this phase?
4. Explain what is occurring at phase E.

What is the name of the process that produces gametes?
(1) Mitosis
(2) Binary fission
(3) Asexual reproduction
(4) Meiosis

Cells such as nerve cells and muscle cells reproduce by the process of
(1) meiosis
(2) mitosis
(3) binary fission
(4) budding

Which statement is true about sexual reproduction?
1. It produces offspring with half the number of chromosomes as the parent.
2. It involves sex cells joining together.
3. It produces offspring that are genetically identical to the parents.

The result of meiosis are daughter cells that have
1. half the number of chromosomes
2. a quarter of the number of chromosomes
3. double the number of chromosomes
4. the same number of chromosomes

As a result of mitotic cell division, a cell having 40 chromosomes gives rise to two cells each of which has a chromosome number of _______ chromosomes.
