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.
D, the black squirrels have survived because black has provided them with an advantage in this environment.
When the organism dies in a moist or wet area the organism gets covered in mud and the mud hardens like a rock.
