Cyril Dean Darlington FRS [1] (19 December 1903 – 26 March 1981) was an English biologist, cytologist, geneticist, and eugenicist. He discovered the mechanics of chromosomal crossover, [2] its role in inheritance, and thus its importance to evolution. He was the Sherardian Professor of Botany at the University of Oxford from 1953 to 1971.
While the cytologist's primary responsibility is to discern whether cancerous or precancerous pathology is present in the cellular sample analysed, other pathologies may be seen such as: microbial infections: parasitic, viral, and/or bacterial; reactive changes; immune reactions; cell aging; amyloidosis; autoimmune diseases
The G phase – which is the cell growth phase – makes up approximately 95% of the cycle. The proliferation of cells is instigated by progenitors. All cells start out in an identical form and can essentially become any type of cells. Cell signaling such as induction can influence nearby cells to determinate the type of cell it will become.
A metaphase cell positive for the BCR/ABL rearrangement using FISH. Cytogenetics is essentially a branch of genetics, but is also a part of cell biology/cytology (a subdivision of human anatomy), that is concerned with how the chromosomes relate to cell behaviour, particularly to their behaviour during mitosis and meiosis.

A cytotechnologist at work (1992). Cytotechnology is the microscopic interpretation of cells to detect cancer and other abnormalities. [1] This includes the examination of samples collected from the uterine cervix (), lung, gastrointestinal tract, or body cavities.

Clarence Erwin McClung (April 5, 1870 – January 17, 1946) was an eminent American zoologist and prairie pioneer cytologist who discovered the role of chromosomes in sex-determination.
