During ooplasmic segregation in ascidians, the myoplasm moves from its original location in the periphery of the unfertilized egg to the vegetal pole of the zygote. The vegetal cap of myoplasm marks the future site of gastrulation and the dorsal side of the embryo. The purpose of this investigation was to determine the mechanism for polarizing the myoplasm during ooplasmic segregation. To test the possibility that the myoplasm moves toward the sperm and that the vegetal pole is the exclusive… CONTINUE READING
