FlyBase curator comment: genomic coordinate updated from release 5 coordinate ( X:17 ,432,002) given in paper.
This Dp(1;1)B breakpoint lies in an intergenic region downstream of B-H2 and upstream of B-H1, and contains a roo element in the 5' to 3' orientation. FlyBase curator comment: genomic coordinate updated from release 5 coordinate ( X:17 ,228,526) given in paper.
A roo-element insertion at the 16A7 breakpoint.
Position-effect apparently resulting from juxtaposition of 16A1 with 16A7, which may undergo mutation to less extreme forms (e.g., Bi). Produces normal and triplicated Dp(1;1;1)BB products by unequal crossing over.
