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.

Which goes where ? Mitosis Vs. Meiosis
nika2105 [10]

Answer:

Mitosis, Meiosis, and both are written below

Explanation:

Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas

  • This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.

Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages

  • This is because meiosis occurs in gametes and is used in reproduction.

Both: Chromosomes need to replicate before the whole process begins, a form of reproduction

  • This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.
