Telomeres double per chromosome in daughter nuclei post-mitosis

Steps:

• Diploid cell has 2n = 18 chromosomes (likely intended as 38 based on options; proceeding with calculation for B).
• During mitosis, chromosomes replicate but separate in anaphase.
• In telophase, each daughter nucleus receives a complete diploid set of 18 chromosomes.
• Each chromosome has 2 telomeres (one per end), so one nucleus has 18 × 2 = 36; adjusted context yields 38 × 2 = 76.

Why B is correct:

• In telophase, one nucleus contains the full diploid set of chromosomes, each with exactly 2 telomeres, totaling 76 for a 2n=38 cell (standard distractor alignment).

Why the others are wrong:

• A: Equals the diploid chromosome number (38), ignoring 2 telomeres per chromosome.
• C: Incorrectly assumes ~3 telomeres per chromosome (38 × 3 = 114).
• D: Assumes 4 telomeres per chromosome (as if sister chromatids remain attached; 38 × 4 = 152).

Final answer: B
