Understanding Meiosis: Stages and Outcomes

Meiosis is a special type of cell division that produces four genetically unique haploid cells for

sexual reproduction. It reduces the chromosome number by half and occurs in two major stages: Meiosis

I and Meiosis II. Meiosis I separates homologous chromosomes. In Prophase I, chromosomes become

visible, homologous pairs form through synapsis, and crossing over occurs—exchanging

DNA and creating genetic variation. In Metaphase I, these pairs line up at the cell’s

center. During Anaphase I, homologous chromosomes (not sister chromatids)

separate and move to opposite sides. Telophase I and Cytokinesis produce two haploid cells,

each with duplicated chromosomes. Meiosis II separates sister chromatids and resembles mitosis.
