1

meiosis has ___ DNA replication followed by ___ cell divisions

one, two

2

can meiosis occur in haploid cells?

no, it requires a diploid cell with pairs of homologs

3

the end result of meiosis is

to make haploid cells for the haploid stage

4

meiosis I stages

prophase I, metaphase I, anaphase I, telophase I

5

meiosis II stages

prophase II, metaphase II, anaphase II, telophase II

6

meiosis I separates ____ and meiosis II separates ___

homologs, sister chromatids

7

homolog behavior in meiosis I

pair up parallel to each other with gene loci matching

form a physical unit called a bivalent/tetrad

8

one bivalent consists of ___ homologs, or 4 ____

2, chromatids

9

synapsis

the zipping-up of a pair of homologs

10

after homologs undergo synapsis they...

recombine with each other

the homologs then separate and 2 daughter cells are formed

11

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

haploid

12

after meiosis II the daughter cells are still considered....

haploid

13

what phase takes up most of the time in meiosis?

prophase I of meiosis I

14

is meiosis II brief?

yes
