Which phase of cellular meiosis is characterized by the pairing of homologous chromosomes and crossing over, allowing genetic recombination between non-sister chromatids?

💡 Solution & Explanation

Prophase I of meiosis is subdivided into stages including leptotene, zygotene, pachytene, diplotene, and diakinesis, where homologous chromosomes synapse and undergo crossing over to exchange genetic material. Metaphase I involves alignment along the equatorial plate, while anaphase separates homologous pairs. Genetic diversity in sexually reproducing organisms originates during this recombination phase.
