Question

what do you recall is the outcome of meiosis i, which is different to the outcome of mitosis?
two genetically identical cells
two genetically different cells
more than two genetically identical cells
more than two genetically different cells
one new cell

Explanation:

To solve this, we recall the processes of meiosis I and mitosis:

• Mitosis results in two genetically identical daughter cells (diploid, same as parent).
• Meiosis I involves homologous chromosome separation and crossing - over, producing two haploid cells that are genetically different from the parent and from each other.
• Option 1: Mitosis (not meiosis I) gives two identical cells.
• Option 3: Mitosis and meiosis I don't give more than two cells at this stage (meiosis II later gives four, but I gives two).
• Option 4: Meiosis I gives two, not more than two, cells.
• Option 5: Neither mitosis nor meiosis I result in one new cell.

So the outcome of meiosis I is two genetically different cells.

Answer:

B. Two genetically different cells
