Meiosis is the process of cell division that produces gametes, such as sperm and egg cells. It involves two rounds of cell division, resulting in four daughter cells with half the number of chromosomes compared to the original cell. The first division, meiosis I, separates the pairs of homologous chromosomes so that each daughter cell receives one chromosome of each pair. The second division, meiosis II, separates sister chromatids so that a total of four gametes are produced with only one set of chromosomes.

1. Meiosis

2. What is Meiosis??
• It is the process of cell division in mammals
and other organisms and creates a gamete.
• It is the division of a diploid nucleus with only
one replication of DNA.

3. Meiosis 1
• First interphase happens as well as DNA
replication.
• Meiosis I is the first nuclear division which
occurs into five different stages, prophase I,
metaphase I, anaphase I, telophase I, and
cytokinesis.

4. How is Phrophase I different in
Meiosis?
• Synapsis happens which is the formation
along the length of the chromatids of a zipper
like structure that aligns the two homologs
precisely.
• Tetrad occurs with four chromatids in a
synapsed set of homologous chromosomes.

5. Metaphase I
• The homologs line up two by two on the
equatorial place versus one by one in mitosis.

6. Anaphase I
• The tetrad seperates so that the homologous
pairs disjoin and migrate toward a pole.

7. Telophase I
• The nuclear envelope is formed around the
homologous pairs.
• Cytokinesis begins

8. Cytokinesis
• Two cells that are 2 are then ready to start
Meiosis II

9. The second steps:
• The second steps of Meiosis are similar to the
first steps except now there are two cells
being divided at once and then at the end
there is a total of four gametes.
