Alignment of the sister chromatids along the equatorial plate. Alignment of the sister chromatids along the equatorial plate occurs during metaphase II, the stage where oocyte arrest takes place following ovulation and prior to fertilization. Alignment of the homologous chromosomes along the equatorial plate Alignment of the homologous chromosomes along the equatorial plate occurs during metaphase I. Migration of sister chromatids to opposite poles Migration of sister chromatids to opposite poles occurs during anaphase II. Migration of homologous chromosomes to opposite poles Migration of homologous chromosomes to opposite poles occurs during anaphase I. Physiology A researcher studying the process of ovulation in human females recruits 10 female volunteers. He injects subcutaneously human chorionic gonadotropin (hCG) hormone and retrieves the eggs 35 hours later. Using the appropriate technique, he views the eggs under fluorescence microscopy. Under fluorescence microscopy, which of the following findings does the researcher most likely observe? B Reproductive 2020-10-28T00:13:40Z 2459150.5094907 WBR0338
