Description: This 3D medical animation shows a polar body biopsy procedure. Prior to the procedure, the developing egg, called the primary oocyte, divides into the secondary oocyte and the first polar body. At this point, the biopsy procedure can be performed, during which a needle removes the polar body. Its genetic contents can be examined to diagnose translocations and monogenic disorders of maternal origin. In this animation, the BRCA1 gene, which can lead to an increased risk of breast cancer, is highlighted.
