Since sea urchins being deuterostomes, possess indeterminate cleavage, the separation of one cell from rest of the embryo will result in its growth into genetically identical embryo.
Deuterostomes are those species in which the formation of anus occurs before the formation of their mouth. The anus is formed from the blastopore in them. Deuterostome literally means second mouth. Example of such animals is: starfish, sea urchin, sea lily, sea cucumber, etc.
Indeterminate cleavage is the one where the cells of embryo possess the ability to give rise to complete embryo is they are separated from the actual embryo. Therefore, the cells are said to be totipotent.
