WebApr 11, 2024 · We can think of meiosis as a way cells very carefully count and divide their chromosomes so that each gamete, each egg or sperm, has exactly 23 chromosomes. Then when an egg with its 23 chromosomes is fertilized by a sperm with its 23 chromosomes, the resulting fertilized egg has exactly 46 chromosomes. WebMar 2, 2024 · Fixed metaphase chromosomes were released by mechanical homogenization into LB01 buffer ( 37) and stained by 4',6-diamidino-2-phenylindole (DAPI) at a final concentration of 2 μg/ml. The chromosomes were purified by sorting using a FACSAria SORP flow cytometer (Becton Dickinson, San Jose, CA USA).
