Chromosomes are thread-like structures housed in the center (nucleus) of a cell that warehouse all the genetic information for each and every individual. When cells form in reproductive organs, they start from one fertilized cell (sperm in males, eggs in females), then go through cell division (meiosis), where one cell splits twice to create four cells. .
