Assuming DNA is replicated correctly (so there are no mutations),
gavmur [86]

Answer:

None of the choices would lead to all identical gametes.

Explanation:

Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.

The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.
