Meiosis study guide 2

Question 1

interphase

Answer 1

growth stage

Question 2

prophase I

Answer 2

chromosomes condense and thicken,

homologous chromosomes: same size and contain same types of genes in same locations.

crossing over: transfer of genetic info to create a new and unique genetic code combo

Question 3

metaphase I

Answer 3

chromosomes match up in pair in middle of cell. (parallel to each other).

|~X x~| <—- parallel
|~X x~|
|~X x~|
|~X x~|
|~X x~|

Question 4

anaphase I

Answer 4

chromosomes are pulled apart by spindle fibers

Question 5

telophase I/ cytokineses

Answer 5

2 newly formed nuclei, end of meiosis 1, with 2 new cells/

cytokineses splits the cell into two separate cells

Question 6

prophase II

Answer 6

have chromosomes and spindles start to form, nuclei disappears

Question 7

metaphase II

Answer 7

chromosomes line up in middle but this time they are in a single file line

|~x~| <—- single file line

Question 8

anaphase II

Answer 8

chromatids are pulled away by spindle fibers

|~< >~| <—chromatids pulled away

Question 9

telophase II

Answer 9

nuclei are reforming, now 4 cells are forming/

cytokineses- seperates them so that their are 4 cells with 4 chromosomes in each cell
