A New Method for the Study of Chromosome Rearrangements and the Plotting of Chromosome Maps

Genetics on the Fly: A Primer on theDrosophilaModel System

“…After their discovery in the 1930s in other insects, polytene chromosomes were described in D. melanogaster salivary gland cells (Painter 1933) and established by Bridges (still in Morgan's group after their move to CalTech) as a primary tool for chromosome mapping (Bridges 1935). His meticulous drawings of polytene chromosomes are still in use 80 years later.…”

Small flies—Big discoveries: Nearly a century of Drosophila genetics and development

“…Painter, a student of Theodore Boveri who in 1903 along with Walter Sutton proposed that chromosomes contain genes, discovered the Drosophila giant salivary gland chromosomes. Importantly, Painter understood that this biological material offered an excellent opportunity to visualize chromosome structure (Painter, 1934). Second the societal: Morgan in addition to establishing the fruit fly as a model genetic organism endowed us with a new scientific culture: "The open, critical, yet fully democratic and egalitarian atmosphere that was evident in the Fly Room soon came to characterize the distinctively American atmosphere of university research-an especially significant development as American graduate education increasingly became the model for graduate education throughout the world" (Kandel, 1999).…”

Von der Zellenlehre zur Chromosomentheorie

“…Erst in den dreißiger Jahren unseres Jahrhunderts wurde die Chromoso mennatur der Kernfäden in Dipteren-Zellkernen von Heitz und Bauer (1933), Painter (1933) und King und Beams (1934) sichergestellt. Aus dem Kuriosum wurde eines der ertragreichsten Untersuchungsobjekte der modernen Zytogenetik, das glänzendste Beweismaterial für die Chromosomentheorie der Verer bung vgl.…”
