SEM of first polar body (pb) release. Scale bar = 10 ^m. Figures 5-7. First cleavage with polar lobe formation. Polar lobe (pi) forms at vegetal pole as cleavage furrow (cf) develops at animal pole. Polar lobe fuses with CD blastomere as cleavage becomes complete. LM, bright field optics, pb, polar body. Scale bar = 20 nm. Figure 8. Third cleavage stage. Blastomeres labelled using nomenclature for spirally cleaving embryos. SEM. pb, polar body. Scale bar = 20 jim. 305.
