In humans, a fertilized egg contains 46 chromosomes. Which bar graph best represents the number of chromosomes contained in the sperm and egg before they united to make the fertilized egg?(1 point)

In humans, each sperm and egg cell contains half the number of chromosomes present in a fertilized egg. Since a fertilized egg has 46 chromosomes, both the sperm and egg each carry 23 chromosomes.

Therefore, the bar graph that best represents the number of chromosomes contained in the sperm and egg before they united to make the fertilized egg would show one bar at 23 for the sperm and one bar at 23 for the egg.
