Explanation:

• Analyze Option A: Meiosis has two cycles of cell division (meiosis I and meiosis II), so A is incorrect.
• Analyze Option B: Meiosis involves processes like crossing - over and independent assortment, which result in cells with unique genetic information (gametes), while mitosis produces genetically identical daughter cells. This is a key difference.
• Analyze Option C: Both mitosis and meiosis result in cell division, and mitosis does divide into two new cells, but this is not a difference between them (meiosis also results in cell division, just with different outcomes in terms of number of cells and genetic content). So C is not a differentiating factor.
• Analyze Option D: Mitosis has one cycle of cell division, while meiosis has two. So D is incorrect.

Answer:

B. Cells in meiosis have unique genetic information
