a
The oocyte nucleus must remain centrally located for the dorsal-ventral axis to develop appropriately.

b
The oocyte nucleus is pushed against the ventral surface of the embryo and ensures that ventral structures will develop there.

c
As the oocyte grows, the nucleus is pushed to the side that will later become the dorsal anterior corner.

d
As the oocyte grows, the nucleus becomes compressed and this causes expression of genes that direct polarity.
