It is estimated that there are a total of 245 cells (roughly 50 trillion) in the adult human body. Starting from a fertilized egg, how many cell divisions would be required to produce 245, assuming that every cell divides in every cycle?

45.5 divisions

Explanation:

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells - sperm in males, eggs in females. During meiosis one cell divides twice to form four daughter cells.
