• it produces more genetic variation
• it only requires 1 parent
• it produces exact copies of the parent

Genetic variety occurs in meiosis because of

• independent assortment
• both crossing over and independent assortment

• Each daughter cell gets a copy of its parent's DNA
• It becomes more difficult to get oxygen and nutrients
