Which is the easiest stage of mitosis for counting chromosomes under a microscope?
Aanaphase, when chromatids are mid-separation
Btelophase, when nuclei are re-forming
Cprophase, when chromatin is still condensing
Dmetaphase, when chromosomes line up at the equator
Answer & Solution
Correct answer: D. metaphase, when chromosomes line up at the equator
Metaphase is the cleanest counting stage because all chromosomes sit aligned at the metaphase plate, fully condensed and not yet separating. Karyotype analysis is done on metaphase spreads.
