Meiosis occurs during gamete formation, producing cells with half the normal number of chromosomes. Meiosis constitutes a cycle of reproduction. Meiosis is involved with the reduction in the amount of genetic material. Meiosis is distributed into divisions, with four stages in each division.
Interphase: Before meiosis begins, genetic material is duplicated.
First Division
Prophase 1: Duplicated chromatin condenses; Crossing over can occur during this stage.
Metaphase 1: Homologous align at the equatorial plate
Anaphase 1: Homologous pairs separate with daughter cells remaining together.
Telophase 1: Two daughter cells are formed with each daughter cell containing one chromosome of the homologous pair.
Second Division: Gametes Formation
Prophase 2: DNA does nor replicate
Metaphase 2: Chromosomes align at the equatorial plate
Anaphase 2: Centromeres divide and sister chromatids separate to each pole
Telophase 2: The cell division is complete.
