WebProphase I Meiosis is divided into two phases, beginning with Meiosis I. The first stage of Meiosis I is prophase I. During the beginning of this stage, the chromosomes condense. MORE DETAIL 3.) Crossing Over During the middle of prophase I, homologous chromosome undergo synapsis, or pairing up. Web3 feb. 2024 · Introduction. During meiosis, recombination between paired homologous chromosomes contributes to genetic diversity by introducing new allele combinations (Chen et al. 2024).Recombination is essential for forming physical attachments between homologous chromosomes, which is beneficial for accurate chromosome segregation …
