A scientist who studies the structure and function of cells, especially in relation to genetics and heredity.
The cytogeneticist analyzed the chromosomes to identify genetic disorders.
Cytogeneticist → It is formed from "cyto-" (from Greek "kytos", meaning cell), "genetic" (from Greek "genesis", meaning origin or birth), and "-ist" (meaning one who practices or specializes in). The word refers to a specialist in the study of the genetic composition and behavior of cells.
Think of a 'cell' ('cyto-') specialist who studies the 'origin' ('genetic') of genetic material — that's what a cytogeneticist does.
