At the molecular and cellular level, how does morphogenesis differ from establishment of embryonic axes and the specification of cellular identity?

#Unit 5. Developmental Biology

The formation of embryonic axes and the specification of cell fates rely heavily on gene expression patterns, whereas morphogenesis relies primarily on cell-cell signalling.
The specification of pattern and fate has been presented as being completely under maternal control, whereas morphogenesis concerned with zygotic control over development.
The formation of embryonic axes and the specification of cell fates rely heavily on cell-cell signaling events, and their influence over gene expression patterns, whereas morphogenesis relies primarily on cell-cell adhesion and cell motility.
There is no fundamental difference in mechanism between patterning events such as axis formation and morphogenic events such as gastrulation.
