WebJul 27, 2024 · History and Evolution of Cytogenetics. By Sean Case 07.27.2024. Cytogenetics has been a key part of biology since 1842, when Swiss botanist Karl Nägeli first discovered chromosomes in pollen. In the decades since, the science has been defined as the study of chromosomes, including their behavior, mechanics, and role in inheritance. Following the advent of procedures that allowed easy enumeration of chromosomes, discoveries were quickly made related to aberrant chromosomes or chromosome number. In some congenital disorders, such as Down syndrome, cytogenetics revealed the nature of the chromosomal defect: a "simple" trisomy. Abnormalities arising from nondisjunction events can cause cells with aneuploidy (additions …
