The number and visual appearance of the chromosomes in the cell nuclei of an organism or species is known as what?

• A. Karyotype
• B. Gamete
• C. Diploid Cell
• D. Homozygous

Answer: (A)

This question is about the karyotype—the chromosome portrait of an organism. A karyotype captures both how many chromosomes are present and what they look like under a microscope, arranged by size and shape with their banding patterns visible. It shows the species’ chromosome complement, such as the typical set and any noticeable structural features. This concept is what researchers refer to when they talk about the number and visual appearance of chromosomes in cell nuclei. A gamete, by contrast, carries only one set of chromosomes. A diploid cell has two sets of chromosomes but the term doesn’t describe the visual arrangement or exact count in a systematic way. Homozygous relates to having identical alleles for a gene, not to the overall chromosome number or appearance.
