Answer 11

two times

Question 12

What are the stages of meiosis?

Answer 12

1) Prophase 1
2) Metaphase 1h
3) Anaphase 1
4) Telophase 1
Cytokinesis
Interphase
*the same steps 1-4 occur again only with “2’s” following them
*remember PMAT for the order and names

Question 13

Is DNA copied before meiosis 2?

Answer 13

no

Question 14

How many cells are formed at the end of Meiosis II?

Answer 14

4

Question 15

In humans, how many chromosomes do these cells contain?

Answer 15

23

Question 16

How are DNA and chromosomes related?

Answer 16

chromosomes are made of tightly wound DNA

Question 17

Meiosis vs Mitosis?

Answer 17

Meiosis: 4 cells are formed, 2 cell divisions occur, sex cells and 1/2 DNA
Mitosis: 2 cells are formed, 1 cell division, body cells and same DNA

Question 18

Why do sexually reproducing organisms have to use a second cell division like meiosis?

Answer 18

because you have to cut it in half, if you left the DNA whole you would have to much DNA. You only need a set form each parent.
