Question 10

Homologous chromosomes

Answer 10

Matching pairs of chromosomes

Question 11

Tetrad

Answer 11

Two pairs of homologous chromosomes line up together

Question 12

Synapsis

Answer 12

The exchange of parts of a chromosome in a homologous pair

Question 13

Prophase 1

Answer 13

Homologous chromosomes pair up and crossing over happens

Question 14

Metaphase 1

Answer 14

Homologous chromosomes pair up in the middle of the cell and spindle fibers attach.

Question 15

Anaphase 1

Answer 15

The homologous chromosomes move to opposite pole of the cell.

Question 16

Telophase 1 + Cytokinesis 1

Answer 16

cell begins to divide into 2 genetically unidentical cells.

Question 17

Prophase 2

Answer 17

the chromosomes condense, and a new set of spindle fibers forms

Question 18

Metaphase 2

Answer 18

The homologous pairs of chromosomes line up in the center of the cells and spindle fibers attach

Question 19

Anaphase 2

Answer 19

The sister chromatids break apart and move to opposite sides of the cell

Question 20

Telophase 2 + Cytokinesis 2

Answer 20

Two cells divide forming 4 genetically unidentical cells. New nuclear envelope develop around the chromosome
