Answer:

A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>

Explanation:

G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
A cell cycle has two phases; interphase and M-phase.
During interphase the cell grows and in M-phase it divides.
G1 is the Gap between the M-phase and the S-phase.
G2 is the gap between the S phase and M phase.

DNA replication is confined to the S part of interphase.
Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
