The correct answer to the question is karyotype.

Explanation:

A karyotype is a visual representation of the complete set of chromosomes in an organism, typically arranged in pairs by size and shape. It is often used in genetics to diagnose chromosomal abnormalities or to study the chromosomal composition of a particular species.

In contrast:

• Phenotype refers to the observable characteristics or traits of an organism, such as height, eye color, or behavior, which result from the interaction of its genotype with the environment.
• Genotype refers to the genetic makeup of an organism, specifically the alleles present at specific loci, which can influence the phenotype but is not directly observable like a karyotype.

In summary, a karyotype graphically depicts the arrangement of chromosomes, providing valuable insights into genetic health, while phenotypes and genotypes describe different facets of genetic expression and inheritance.
