Meiosis x Mitosis
Phase
Prophase I
Meiosis I
Chromosomes are
duplicated , chromatids
are visible, nuclear
membrane starts to
disappear
Still in
Prophase I
Duplicated
chromosomes form
pairs called tetrads in a
process called synapsis
Pair of chromosomes
line up in the middle of
the cell and each
duplicated chromosome
is attached to one
spindle fiber only.
Metaphase I
Anaphase I
Telophase I
The chromosomes that
are lined up in pairs
separate to the
opposite poles of the
cell. Each duplicated
chromosome still has 2
chromatids
The cell separates in 2
identical cells and the
duplicated
chromosomes are in the
cells
Meiosis II
Mitosis
Same for Prophase
in Mitosis
Does not happen in
Mitosis
In Mitosis, there are
no pairs of
chromosomes and
the duplicated
chromosomes are
attached to two
spindle fibers,
because the
centromere will split
in two and the
chromatids will
separate
The chromatids are
the ones that
separate
Each new cell had
only one of the
chromatids of each
chromosome.
Nuclear membrane
will form.
Nuclear membrane will
not form
No Cytokinesis will
occur
Prophase II
Metaphase II
Anaphase II
Telophase II
Cytokinesis
Meiosis II (
second division
starts)
Duplicated
chromosomes
and spindle
fibers reappear
in each cell
Duplicated
chromosomes
migrate to the
center of the
cell, each
chromosome
Is connected to
two spindle
fibers, because
now the
chromatids will
separate
Centromere
split in two and
sister
chromatids
separate
Cell start to
divide, nuclear
membrane
forms
Cytokinesis
This is the end of
Mitosis
Cytokinesis will
occur
Only one division
occurs in Mitosis
It is the same in
metaphase in
Mitosis
It is the same for
Anaphase in Mitosis
It is the same for
Telophase in Mitosis
Cytokinesis
