Why is meiosis important for sexual reproduction? 

• It allows the zygote formed from fertilization to have triple the chromosome number of the organism. 
• It allows gametes to have twice the original number of chromosomes of the organism.
• It allows gametes to have half the original number of chromosomes of the organism.
• It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism.

What is the result when a single cell reproduces by meiosis?

• two cells that have twice the genetic information as the parent cell
• two cells that have half the genetic information as the parent cell
• four cells that have twice the genetic information as the parent cell
• four cells that have half the genetic information as the parent cell
