Cytogenetics is the study of chromosomes in cells and how they affect an organism's characteristics, development, and health. This field of research focuses on the structure, function, and abnormalities of chromosomes, including genetic variations such as deletions, duplications, translocations, and inversions. Cytogenetics plays a crucial role in understanding genetic disorders, diagnosing diseases, and studying inheritance patterns. Techniques such as karyotyping, fluorescence in situ hybridization (FISH), and chromosomal microarray analysis are commonly used in cytogenetics research. This area of study is important in fields such as medicine, agriculture, and evolutionary biology.
