Why is meiosis important for sexual reproduction?

• It allows the zygote formed from fertilization to have triple 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.

• If not, then there will be different instructions passed on to the new cell
• It's not important
• It's not important because the cell will just figure it out
