Meiosis
a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell; the production of gametes in sexually reproducing organisms
Meiosis II
The second division of a two-stage process of cell division in sexually reproducing organisms that results in 4 cells with half the number of chromosome sets as the original cell and only 1 copy of each chromosome.
Prophase II
2 cells produced in Meiosis I. Nuclei disappear. Chromosome condense. Spindle fibers appear.

Metaphase II
Chromosomes line up single file in the middle of the cell. Spindle fibers attach to each chromatid.

Anaphase II
Sister chromatids separate.

Telophase II and Cytokinesis
A nucleus forms around each set of unreplicated chromosomes. The two cells divide into 4 haploid cells called gametes.

gametes
created during Meiosis. another name for sex cells.
Haploid
The number of chromosomes in the cells that start and end Meiosis II. The number of chromosomes in the gametes. Half of the number of chromosomes that the process of Meiosis started with.
