Definitions

2. A field of biological science concerned with investigating the properties and arrangement of chromosomes and their role in heredity
3. The scientific discipline dedicated to analyzing chromosomes and nuclear material to understand cellular genetics and inheritance

Etymology: Karyology is the study of cell nuclei and chromosomes, and its name is built from the Ancient Greek "káruon", meaning "kernel" or "nucleus", joined to the familiar "-ology", the suffix for a field of study. The word therefore describes the study of the kernel of a cell, the part that carries genetic material. The Greek "káruon" was a general word for a nut or kernel, the hard seed inside a shell, so the scientific sense grows naturally from an everyday image. Biologists borrowed the same idea when they looked inside cells and found a dense central body, which they named the nucleus, a Latin word with the same meaning. Karyology is thus a scientific coinage built from classical parts rather than a word that existed in ancient times.
