Fish blastodisc
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.

WebLike fish eggs, the yolky eggs of birds undergo discoidal meroblastic cleavage. 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). WebBegining in the late blastula stage, the YSL and the blastodisc spread over the yolk cell, much like pulling a knitted ski cap over your head, in a process known as epiboly. Eventually, at the end of gastrulation, the yolk cell is …
