MEIOSIS An illustration of the process by which
a single parent diploid cell divides to produce
four daughter haploids cells
2
Maternal homologue
Paternal homologue
A single diploid cell
3
Prophase I Each Chromosome duplicates and
remains closely related
4
Metaphase I Homologous Chromosome align at
equatorial plate.
5
Anaphase I Homologous pairs separate with sister
chromatids remaining together
6
Telophase I Two daughter cells are formed with
each daughter containing only one chromosome of
the homologous pair.
Daughter cell containing homologous pairs.
Daughter cell containing homologous pairs.
7
Prophase II DNA does not replicate.
8
Metaphase II Chromosomes align at the equatorial
plate.
9
Anaphase II Centromeres divide and sister
chromatids migrate separately to each pole.
Sister chromatids
Sister chromatids

Sister chromatids
10
Telophase 2 Cell division is complete. Four
haploid daughter cells are obtained.
