Homologous recombination via crossing over occurs during pachytene stage of prophase I in meiosis, mediated by synaptonemal complex and recombination nodules exchanging chromatid segments. This generates genetic variation and ensures proper segregation, absent in telophase, anaphase, and metaphase I.
