The initiation phase begins when morphological development ceases.

Gaupp is best remembered for his research involving the morphological development of the cranium in vertebrates.

At all the temperatures tested there was no cessation of morphological development.

There are, however, a few examples of continued morphological development during diapause.

The vascular system of the erect trunk was unusual in that it switched its morphological development as the plant grew.

Such evidence provides useful insights into the site's morphological development, both inside and outside the central core.

Its morphological development was entirely different from that of the human hand, yet it had brought itself into a fairly approximate similarity.

It is possible that the morphological development observed in diapausing A. pisum is exceptional.

Alternatively, diapause in many other insects may also involve a slowing but not a cessation of morphological development.

On the other hand, the male gamete maturation involves significant morphological development.
