Meiosis

Question 1

purpose of meiosis is to

Answer 1

produce gametes

Question 2

prophase 1

Answer 2

crossover/exchange of chromosomal info between homologous chromosomes

Question 3

metaphase 1

Answer 3

gets ready to separate (independent assortment)
- doesn’t separate centromeres

Question 4

during metaphase 1

Answer 4

kinetochores attach to same pole

Question 5

anaphase 1

Answer 5

• some crossing over
• no centromere split

Question 6

telophase 1

Answer 6

• nucleus reforms
• cells start cytokinesis

Question 7

crossing over is

Answer 7

the physical exchange of regions of chromatids between sister chromatids

Question 8

importance of crossing over

Answer 8

genetic diversity

Question 9

which traits are more likely to be exchanged

Answer 9

the traits on the end

Question 10

No DNA replication in meiosis results in

Answer 10

the reduction of chromosome # from diploid to haploid

Question 11

the chromosomes # is reduced from diploid to haploid because

Answer 11

there is no DNA replication in meiosis because

Question 12

prophase 2

Answer 12

• nuclear envelope disappears
• spindles formme

Question 13

metaphase 2

Answer 13

chromosomes align on the metaphase plate

Question 14

anaphase 2

Answer 14

sister chromatids are separated

Question 15

telophase 2

Answer 15

nuclear envelope re-forms
- cytokinesis follows

Question 16

meiosis produces — cells

Answer 16

haploid that are not identical

Question 17

gamete

Answer 17

egg and sperm cells

Question 18

haploid

Answer 18

1 set of chromosomes that have half of the genetic information

Question 19

synapsis

Answer 19

homologues become closely associated with each other

Question 20

when does synapsis occur

Answer 20

meiosis 1

Question 21

during crossing over…

Answer 21

when forming a connection they trade equal parts
