Question

identical cells after the cell cycle what is the purpose of growing the cell during the g2 phase? to create genetic variation between two cells to prepare the cells for interphase to ensure both new cells start with a good size

Explanation:

During G2 phase, cell growth occurs to make sure daughter - cells are of an appropriate size after division. Genetic variation is not created in G2. Also, G2 is part of interphase, not a preparation for it.

Answer:

to ensure both new cells start with a good size
