Nucleus dissapears
Centrosomes move
to opposite sides of
cell
A centrosome is an organelle near the nucleus of a cell that contains the centrioles (in animal cells) and from which the spindle fibers develop in cell division.
Chromosomes become visable
DNA is copied
Homologous chromosomes pair up
Cross over occurs
Cross-over is when chromosomes cross over
each other and exchange genes
Chromosomes
line up in the
middle of the cell
Meiotic spindle
fibers appear
Spindle fibers
attach to
centromeres
Chromosomes
move away
from pairing
Independent Assortment
Cell pinches
together
Cytoplasm splits
between the two
cells
Nucleus reappears
Subtopic
4 sets of chromatids
2 daughter cells are
present
Nucleus disappears
Spindle fibers form
Chromosomes line up in
the middle of the cell
Spindle fibers attach to centromeres
Sister chromatids are pulled apart
Cells pinch together
cytoplasm separates
nucleus forms in all cells
results in 4
cells
