Definitions:

Metaphase II

A phase of meiosis II where the chromosomes align at the metaphase plate, similar to metaphase in mitosis, but this process occurs in a haploid set of chromosomes.

Meiosis

Process in which a 2n cell undergoes two successive nuclear divisions (meiosis I and meiosis II), potentially producing four n nuclei; leads to the formation of gametes in animals and spores in plants.

Prophase II

The first stage of meiosis II, where the genetic material condenses into visible chromosomes, preparing for eventual separation into daughter cells.

Metaphase I

A stage of meiosis where homologous chromosomes pair up and align along the equatorial plate of the cell.
