Which term refers to the number and visual appearance of the chromosomes in the cell nuclei of an organism or species?

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

Answer: (D)

This question is about naming the term that describes both how many chromosomes happen to be in a cell’s nucleus and how those chromosomes look when we observe them under a microscope. The karyotype is the complete set of chromosomes for an organism, shown together in terms of their number and appearance (size, shape, and banding patterns) in a chart or chart-like arrangement. It’s what scientists use to see the chromosomal complement of a cell, compare species, or spot abnormalities. The other terms refer to specific states or cell types rather than the full chromosomal picture. A diploid cell has two complete chromosome sets, a haploid has one, and a gamete is a reproductive cell carrying a single set. None of those alone conveys the full number and visual arrangement of chromosomes like a karyotype does.
