Analysis of Caenorhabditis elegans syp-1 mutants reveals that both synapsis-dependent and -independent mechanisms contribute to stable, productive alignment of homologous chromosomes during meiotic prophase. Early prophase nuclei undergo normal reorganization insyp-1 mutants, and chromosomes initially pair. However, the … Webb2 apr. 2024 · Question step 3. Answer: During the prophase of meiosis We you can find overall 5 amounts. Of those when you look at the pachytene the entire process of crossing-over occurs ranging from homologous chromosomes since chromosomes started close one another developing synapsis. Question 4.
