Why meiosis produces haploid cells

Cells are haploid because homologous pairs of chromosomes have been segregated. However, each chromosome is double stranded, having two sister chromatids due to DNA replication before meiosis began.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
