Mitosis vs Meiosis

How is the number of chromosomes in a human sex cell different from the number in a human body cell? 

• A sex cell has 23 chromosomes and a body cell has 46. 
• A sex cell has 46 chromosomes and a body cell has 23.
• A sex cell has chromosomes that are half
• A sex cell has chromosomes that are twice as long as those in a body cell.
