Linguistic Origin & Historical Etymology

The term combines 'chromosome', derived from the Ancient Greek 'chroma' (color) and 'soma' (body), coined by Heinrich Waldeyer in 1888, with 'crossover', describing the physical crossing over of chromatids during meiosis. The concept of genetic crossing over was established by Thomas Hunt Morgan and his colleagues in the early 20th century.
