Meiosis
Meisosis 1 - chromosomes in a diploid cell resegregate, producing four haploid daughter cells
Meiosis 2 - the sister chromatids within the two daughter cells separate, forming four new haploid gametes
Interphase
metaphase 1
anaphase 1
pro metaphase 1
prophase 1
telophase 1
metaphase 2
anaphase 2
pro metaphase 2
telophase 2
prophase 2
the crossing over and recombination of genetic material between non sister chromatids
this results in the genetically unidentical, haploid daughter chromatid cells
disintegration of the nuclear envelope
migration of centrosomes to either pole
These are the condensing of chromatin into chromosomes
the reconstruction of the spindle apparatus.
the nuclear envelopes are completely broken down, and each sister chromatid forms an individual kinetochore that attaches to microtubules from opposite poles
sister chromatids are pulled apart by the kinetochore microtubules and move toward opposite poles.
alignment of chromosomes along a single plane in the center of the cell.
nuclear membranes form around each set of chromosomes, and the chromosomes decondense
cytokinesis
plits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid.
The second stage of the first meiotic division (meiosis I), during which the nuclear envelope breaks down, allowing microtubule access to chromosomes.
encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis
This mechanism separates homologous chromosomes into two separate groups.
third stage of meiosis I and follows prophase I and metaphase I
This stage is characterized by the movement of chromosomes to both poles of a meiotic cell via a microtubule network known as the spindle apparatus
phase when the chromosomes have finished moving to opposite ends of the cell.
Cytokinesis
physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells
In this phase, the cell increases in mass in preparation for cell division
