Question

Quizplus · Accepted Answer

Symmetrical division leads to an increase in the number of cells of a particular lineage, while asymmetrical division produces two cells that differ in fate. The end of the period of asymmetrical division is marked by the activation of apoptosis genes, which result in the death of some cells and the differentiation of others. This ensures the proper formation and organization of the developing organism.
