Chapter 11

Question 1

what is common between mitosis and meiosis

Answer 1

they both divide the nucleus

Question 2

what kind of cells does mitosis make?

Answer 2

body

Question 3

what kind of cells does meiosis make?

Answer 3

sex cells

Question 4

prophase in meiosis

Answer 4

chromosomes thicken, match with homologous pairs bind by tetrad & cross over

Question 5

crossing over is means the chromosomes are now….

Answer 5

recombinant chromosomes

Question 6

prophase in mitosis and prophase 2 in meiosis

Answer 6

nuclear membrane broken down, and chromosomes thicken and condense

Question 7

metaphase in mitosis

Answer 7

chromosomes line up on the metaphase plate

Question 8

anaphase in mitosis

Answer 8

chromosomes pulled away by spindles to opposite ends/poles

Question 9

metaphase 1 in meiosis

Answer 9

chromosomes pair in the middle

Question 10

anaphase 1

Answer 10

homolog chromosomes pulled to opposite sides of cell

Question 11

prophase 2

Answer 11

chromosomes condense, membrane broken

Question 12

metaphase 2

Answer 12

chromosomes line up on metaphase plate

Question 13

anaphase 2

Answer 13

chromatids pulled away to opposite ends/poles

Question 14

telophase 2

Answer 14

nuclei are forming to make 2 cells

Question 15

cytokinesis (in telophase 2)

Answer 15

completely splits cytoplasm, ends w 4 identical gametes

Question 16

sexual reproduction

Answer 16

1 gamete from each parent combines in fertilization

Question 17

genetic diversity

Answer 17

mixing chromosomes from two individuals

Question 18

gene

Answer 18

specific coding on chromosomes, to make traits

Question 19

locus

Answer 19

gene’s specific location along chromosome

Question 20

asexual reproduction

Answer 20

indiv. passes on gene without fusion

Question 21

clone

Answer 21

genetically identical indv. from same parent

Question 22

how many divisions does mitosis or meiosis have

Answer 22

mitosis:1 meiosis:2

Question 23

where do homologs pair from in meiosis

Answer 23

tetrad

Question 24

what type of body cells does mitosis make

Answer 24

clones

Question 25

meiosis makes

Answer 25

sex cells, 4 diff gametes

Question 26

meiosis reduces.. and mitosis does NOT

Answer 26

1/2’s the number of chromosomes

Question 27

where does DNA replication take place in mitosis

Answer 27

(s phase) during interphase

Question 28

where does synapsis (fusion) of chromosomes happen

Answer 28

prophase w crossing over (meiosis)

Question 29

number of daughter cells in mitosis

Answer 29

genetically identical to parent cells

Question 30

of daughter cells in meiosis

Answer 30

4 , each haploid genetically diff from parent cell

Question 31

mitosis role in animals

Answer 31

produce cells for growth

Question 32

meiosis in animals

Answer 32

produces gametes, spores and reduces chromosomes by 1/2
