A chart that visually arranges all the chromosomes of an organism in homologous pairs from largest to smallest is called what?

• A. Chromosome
• B. Genome
• C. Chromatogram
• D. Karyotype

Answer: (D)

The main concept here is how scientists visualize all of an organism’s chromosomes in a structured way. A chart that lines up every chromosome as homologous pairs from largest to smallest is a karyotype. This arrangement lets researchers see the number of chromosomes and spot any large-scale changes in structure, such as extra or missing chromosomes or big rearrangements. A chromosome refers to a single chromosome, not the whole chart. A genome is the complete set of genetic material for an organism, not a visual arrangement. A chromatogram is a graph produced during DNA sequencing, not a chromosome layout. So the chart described is the karyotype.
