Mitosis vs Meiosis: Key Concepts and Differences

The video tutorial compares mitosis and meiosis, explaining that mitosis occurs in somatic cells and results in two identical diploid daughter cells, while meiosis occurs in gamete cells, producing four genetically diverse haploid cells. Mitosis is for growth and repair, whereas meiosis is for sexual reproduction. Key differences include chromosome behavior during prophase and metaphase, and the number of cell divisions. Genetic diversity in meiosis is achieved through crossing over and independent assortment.

Where does meiosis occur in males?

• Liver

• Brain

• Testes

• Heart

What type of cells does mitosis start with?

• Haploid cells

• Diploid cells

• Dead cells

• Cancerous cells

How many daughter cells does meiosis produce?

• One

• Two

• Three

• Four

During which phase do chromosomes pair up in meiosis?

• Prophase 1

• Metaphase

• Telophase

• Anaphase

What allows for independent assortment in meiosis?

• Single file line of chromosomes

• Double file line of chromosomes

• Random mutation

• Cell division

What is the main goal of mitosis?

• To reduce chromosome number

• To increase body size

• To repair injuries

• To create gametes

What is unique about the cells produced by meiosis compared to the parent cell?

• They have half the genetic material

• They are genetically identical

• They are larger

• They have double the genetic material

Why is genetic diversity important in sexual reproduction?

• It increases mutation rate

• It simplifies genetic makeup

• It decreases offspring health

• It helps create stronger offspring
