Cytogenetics is one of the branches of genetics which deals with the study of the structure of the DNA that is located inside the nucleus of the cell. The nuclear DNA undergoes condensation during the division of the cells. This condensation leads to the formation of structures known as chromosomes.
The number and the form and structure of the chromosomes are also discussed under this field. This is a characteristic of a species that the total number and the morphology of the chromosomes in a cell remain the same. The modern technique of cytogenetics i.e. FISH is used in order to look at the genetic material of the cell.
