Mitosis Produces Identical Daughter Cells

Steps:

• Recall mitosis divides one cell into two genetically identical daughter cells, each with the same chromosome number as the parent.
• Identify the starting cell's chromosome configuration (typically replicated chromosomes aligned).
• After one mitotic division, expect two separate cells, each containing a full, identical set of chromosomes.
• Compare diagrams to find the one showing two such identical nuclei or cells post-division.

Why B is correct:

• Diagram B depicts two daughter cells, each with an identical diploid (2n) set of chromosomes, matching the definition of mitosis as equitable nuclear division.

Why the others are wrong:

• A shows a single cell with unreplicated chromosomes, representing interphase before mitosis.
• C displays replicated chromosomes in one cell, indicating prophase or metaphase of mitosis.
• D illustrates four cells, suggesting two divisions (meiosis or second mitosis).

Final answer: B
