No heterochromatin was found in the Xenopus embryo during the blastule stage. Condensation of chromatin started during the gastrula stage, to increase during the early neurula phase, and to assume the pattern known from mature cells by the late neurula phase. Heterochromatinization signifies cell differentiation and is associated with the incorporation of histones.
