Karyotype is?

• A. A picture of chromosomes arranged by size and shape
• B. A chart showing gene frequencies in a population
• C. A map of metabolic pathways
• D. A picture of chromosomes arranged by size and shape

Answer: (D)

A karyotype is a picture of the chromosomes arranged by size from largest to smallest, often showing their banding patterns. This visual ordering lets you check both how many chromosomes are present and whether their structure is normal. It’s a key tool for detecting chromosomal abnormalities, such as extra or missing chromosomes or structural changes like deletions or translocations, which can underlie certain genetic disorders. Karyotypes are commonly used in prenatal testing and in cancer cytogenetics to understand chromosomal changes in cells. It’s not a chart of gene frequencies in a population, nor a map of metabolic pathways, which are different kinds of information entirely.
