Figure 1. Origin and Genetic Structure of Dp1187.

Figure 1

The origin of the ln(1)sc8 progenitor chromosome from a normal X chromosome and its subsequent derivitization to produce Dp1187 is diagrammed schematically (not drawn to scale). See text and Lindsley and Grell (1968) for further details. A genetic map showing the ten known complementation groups from the X tip that remain on Dp1187 is drawn below. Heterochromatin is shown as a stippled box and euchromatin as a solid line.
