• 20
• 40
• 80
• 160

function of mitosis

• genetic diversity though sexual reproduction
• cell reproduction and general growth and repair

A guinea pig cell has 64 chromosomes.  After mitosis, each daughter contains ___ chromosomes.

• 128

• 64

• 32

• 16

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.
