Imprecise excision of the progenitor insertion, resulting in a 2405bp deletion (coordinates 3R:21306126..21308530 , release 5 genome) which removes part of the XNP locus.
2405 bp deletion resulting from the imprecise excision of P{EP}XNPEP635 (coordinates 3R:21306126..21308530 , release 5 genome).
XNP5/XNP5 (but not XNP5/+) suppresses the variegation of the w locus which is seen in the In(1)wm4h chromosome.
XNP5/XNP5 suppresses the variegation of the w locus which is seen in the P{hsp26-pt-T}39C-5 and P{lacW}50C.x6 insertion lines.
XNP5/XNP5 does not suppress the variegation of the y and w loci which is seen in the P{SUPor-P}KV161 insertion line.
