WebJul 19, 2024 · Recombination is an integral part of the pairing of homologous chromosomes. It occurs between non-sister chromatids during the pachytene stage of meiosis I (the first stage of meiosis) and possibly before, when the homologous chromosomes are aligned in zygotene (Figure 8.3). The crossovers of recombination are visible in the diplotene phase. WebFurther, in the diplotene stage of prophase I of meiosis, each chromosome splits longitudinally into two chromatids.
