Meiosis

Question 1

meiosis has ___ DNA replication followed by ___ cell divisions

Answer 1

one, two

Question 2

can meiosis occur in haploid cells?

Answer 2

no, it requires a diploid cell with pairs of homologs

Question 3

the end result of meiosis is

Answer 3

to make haploid cells for the haploid stage

Question 4

meiosis I stages

Answer 4

prophase I, metaphase I, anaphase I, telophase I

Question 5

meiosis II stages

Answer 5

prophase II, metaphase II, anaphase II, telophase II

Question 6

meiosis I separates ____ and meiosis II separates ___

Answer 6

homologs, sister chromatids

Question 7

homolog behavior in meiosis I

Answer 7

pair up parallel to each other with gene loci matching

form a physical unit called a bivalent/tetrad

Question 8

one bivalent consists of ___ homologs, or 4 ____

Answer 8

2, chromatids

Question 9

synapsis

Answer 9

the zipping-up of a pair of homologs

Question 10

after homologs undergo synapsis they…

Answer 10

recombine with each other

the homologs then separate and 2 daughter cells are formed

Question 11

after meiosis I, the two daughter cells are already considered to be ___

Answer 11

haploid

Question 12

after meiosis II the daughter cells are still considered….

Answer 12

haploid

Question 13

what phase takes up most of the time in meiosis?

Answer 13

prophase I of meiosis I

Question 14

is meiosis II brief?

Answer 14

yes
