Gastrulation typically involves a denting of the hollow ball that is the blastula, so that it becomes two-layered with an opening to the outside world see the computer simulation on p.

Gastrulation is affected in two gene groups, the phenotypes of which display a partial dorsalisation or ventralisation (56,57).

Gastrulation in the fish involves several morphogenetic movements, such as involution of mesendodermal regions and dorsal convergence

Gastrulation is still more modified and curtailed cenogenetically in the placentals than in the marsupials.
