D. melanogaster
FlyBase ID
Sequence coordinates
Member of large scale dataset(s)

After generating all the Dp(1;Y)BSC chromosomes as described in FBrf0212582, we calculated the minimal euchromatic coverage of the X chromosome provided by these duplications as 97.0%.

Series of Dp(1;Y) stocks carrying segments of the X chromosome on the tip of Y chromosome; in an isogenic background. At the time of publication (FBrf0212582), the Dp(1;Y) collection provided a minimum of 78% coverage with duplication breakpoints spaced a median of nine genes apart.

Comments on Cytology

The cytologically observed breakpoints may not represent the full extent of the duplicated segment, because euchromatic bands juxtaposed to centric heterochromatin may not be visible.

The polytene bands closest to the chromocenter in squashes appear to be from region 10.
