Answer 1

interphase 1, prophase 1, metaphase 1, anaphase 1, telophase/cytokinesis 1, prophase 2, metaphase 2, anaphase 2, telophase/cytokinesis 2

Question 2

What happens during interphase 1?

Answer 2

cell prepares for division

Question 3

What happens during prophase 1?

Answer 3

crossing over occurs and tetrads form

Question 4

What happens during metaphase 1?

Answer 4

tetrads line up in the middle, spindle fibers attach and independent assortment occurs

Question 5

What happens during anaphase 1?

Answer 5

tetrads are pulled apart by spindle fibers

Question 6

What happens during thelophase/cytokinesis 1?

Answer 6

Two cells are formed each with 2 chromosome pairs

Question 7

What happens during prophase 2?

Answer 7

spindle fibers start to form

Question 8

What happens during metaphase 2?

Answer 8

chromosomes line up

Question 9

What happens during anaphase 2?

Answer 9

chromosomes are pulled apart to opposite sides of the cells

Question 10
