Meiosis II is division which produces nuclei in cells for a total of nuclei.

Meiosis II is reduction  division which produces four nuclei in 4 haploid cells for a total of four nuclei.

Explanation:

Meiosis 2 is the second phase of meiosis in which each diploid cell gives 2 haploid cells forming four haploid cells. It takes place in eukaryotic cells in gametes or germ cells. Sister chromatids separate in meiosis 2.

It comprises following stages:

prophase II : nuclear membrane breaks down as chromosome condense. spindle fibres get formed and microtubules prepare to grip chromosome.

metaphase II : The chromosomes are lined at metaphase plate.

Anaphase II: the sisters chromatids gets pull apart.

telophase II : nuclear memebrane is formed around each pair of chromosomes, decondensation of chromosomes occur and cytokinesis follow making four haploid cells.
