Cytogenetics

Cytogenetics is the branch of genetics which deals with cytology: cell structure and function. It includes the study of chromosomes, chromosome bands, karyotypes, and cell division, especially meiosis.^[1] Cytogenetic studies have also been used to study evolution in natural populations.^[2]
