mitosis/meiosis comparison

Question 1

of cell divisions

Answer 1

mitosis: one
meiosis: two

Question 2

of chromosomes in daughter cell vs. parent cell

Answer 2

mitosis: same
meiosis: half

Question 3

DNA content of daughter cells vs. parent cell

Answer 3

mitosis: reduced to 1/2, chromosomes go from replicated to unreplicated
meiosis: reduced to 1/4 bc chromosomes go from replicated diploid sets to replicated haploid sets to unreplicated haploid sets

Question 4

synapsis of homologs

Answer 4

mitosis: no
meiosis: yes

Question 5

microtubule attachment

Answer 5

mitosis: individual chromatids in each chromosome attach to microtubules from different spindle poles
meiosis: both chromatids in each chromosome attach to microtubules from same spindle pole

Question 6

of crossing over events

Answer 6

mitosis: none
meiosis: one or more per pair of homologous chromosomes

Question 7

makeup of daughter cells

Answer 7

mitosis: identical
meiosis: different

Question 8

role in life

Answer 8

mitosis: asexual reproduction
meiosis: halving the number of chromosomes in cells that will produce gametes
