WebQuestion: how does Starfish development, starfish fertilized polar bodies, Frog early and late cleavage, Frog and starfish blastula, and White fish blastodisc relate to the stage of embryonic development? 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.
