Mitosis and Meiosis Sequence STAAR

Why do we need meiosis?

• To double the number of chromosomes going into sex cells
• To halve the number of chromosomes going into sex cells
• To triple the number of chromosomes going into sex cells
• To not change the number of chromosomes going into sex cells

What would happen if you are injured and the cell cycle is stopped in your body?

• You would form cancer

• The injury wouldn't heal

• You would mutate

What is happening during crossing over in Meiosis?

• chromatids are replicating

• chromatids are exchanging genetic information

• chromatids are changing color

• chromatids are being deleted

• most of your chromosomes from your mother
• most of your chromosomes from your father
• a random number of chromosomes from each parent
• half your chromosomes from your mother and half from your father.
