Fertilization and early embryonic development in poultry

Poult Sci. 1993 May;72(5):874-81. doi: 10.3382/ps.0720874.

Abstract

There are two major controllers of development in the early stages of bird embryos. These are: 1) gravity, probably acting through the distribution of yolk and its components, which lays down the initial plans for polarity that are later established firmly through the genes; and 2) the primitive streak, which controls the orderly ingression of the cells and imposes a pattern on the developing tissues.
