Meiosis Interactive Video

What is the main purpose of meiosis?

• To produce identical body cells

• To duplicate the DNA within cells

• To generate genetic diversity through gametes

• To repair damaged cells

How many chromosomes do human gametes have?

• 12 pairs of chromosomes

• 92 chromatids

• 23 chromosomes

• 46 chromosomes

What significant event occurs during prophase I of meiosis?

• Chromosomes duplicate

• Chromosomes align in the middle of the cell

• Nuclei reform

• Crossing over of genetic material

How many cells are produced at the end of meiosis?

• 2 cells

• 4 cells

• 8 cells

• 1 cell

What can result from nondisjunction during meiosis?

• Genetic disorders due to incorrect chromosome number

• Cells with the correct number of chromosomes

• Increased genetic diversity

• Production of identical gametes
