MICROSCOPIC OBSERVATIONS OF CRYPTIC POLAR BODY PRODUCTION AND SPIRALIAN ORGANIZATION IN ThE EGG OF ILYANASSA OBSOLETA
Abstract:
Light microscopy of semi-thin sections and scanning electron microscopy reveal a pit at the animal pole of Ilyanassa obsoleta during Meiosis I. The incipient polar body is within the pit. Sections show the spindle at an oblique angle to the egg axis, an early expression of the spiralian organization of this egg. Surface changes on the incipient polar body are similar to those described by others for the polar lobe of Nassarius reticulatus.
