Which process is shown in the image?

• crossing over

• independent assortment

• segregation

• mutation

Crossing over is important because....

• It prevents mutations from entering the gametes. 
• It allows for even distribution of chromosomes in the gametes.
• It allows for more genetic diversity of gametes.
• It allows for genetic uniformity of gametes.
