Answer:
condensation of chromatin in preparation of nuclear division in both cells
Step-by-step explanation:
Mitosis, as a type of cell division, is divided into Interphase and the Mitotic phase. The interphase further comprises of G1, S and G2 phases while the mitotic phase consists of mitosis and cytokinesis.
Mitosis is a form of nuclear division i.e. separation of genetic material (chromosome). According to this question, chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle.
Since what occurs in the M phase of the cell cycle is nuclear division, then fusion of a cell in G1 with a cell in early M phase would most likely result in "the CONDENSATION OF CHROMATIN in preparation of NUCLEAR DIVISION in both cells".
