What does a karyotype display?

• A. All mitochondria in a cell
• B. All genes in a cell
• C. All proteins in a cell
• D. All chromosomes in a cell

Answer: (D)

A karyotype is a visual arrangement of the cell’s chromosomes, organized by size and shape. It displays the complete chromosome complement—the number and structure of all chromosomes in a cell—so you can see if any are missing, extra, or rearranged. This makes it possible to detect large-scale chromosomal abnormalities, like extra copies (trisomies) or structural changes. It does not show mitochondria, which are organelles, nor does it list genes or proteins directly, since it focuses on whole chromosomes and their morphology rather than DNA sequence or protein products.
