Cleavage occurs only in the blastodisc, a small disc of cytoplasm 2–3 mm in diameter at the animal pole of the egg cell. The first cleavage furrow appears centrally in the blastodisc, and other cleavages follow to create a single-layered blastoderm (Figure 11.8).
WebBlastodisc formation takes advantage of the pre-existing biased distribution of cytoplasmic and yolk components of the oocyte. After egg activation, this bias is enhanced by the animal pole-oriented streaming of ooplasm, a process that results in the separation of ooplasm from the yolk and lifting of the animal cortex to form a one-cell embryo.
