Meiosis - Coggle Diagram
Meiosis
Creates sex cells that each contain half genetic material
cells match to make full DNA
Used for reproduction only
Allows for genetic variation
Makes four haploids
n
2 haploids=diploid
2n
Meiosis 1
Prophase 1
Chromsomes pair up(crossing over
creates genetic variation
explains why kids have different traits
Metaphase 1
Chromsomes line up in the middle
Spindle fibers attatch to the chromsomes
Anaphase 1
Chrosomes get pulled apart
Move to the sides of the cell
Telophase 1/Cytokensis
Cells "pinch" in the middle of their cells
cells split apart
Sames phases as mitosis
2 cycles of PMAT
Meiosis 2
Prophase 2
Cells fully split into the two daughter cells
Metaphase 2
Chromsomes line up at the equator
on top of each other instead of side like before
Anaphase 2
Sister chromatids are pulled apart
Chromatids do not count as a chromsome chrosomes are counted by centromeres
Telophase 2/Cytokinesis
2 daugther spells split again
Chromatids pinch in the middle of new grandaughter cells
Ends in four grandaughter cells
