In Drosophila melanogaster, black body (b) is recessive to gray body (B), purple eyes (pr) are recessive to red eyes (PR), and vestigial wings (vg) are recessive to normal wings (VG). The loci coding for these traits are linked, with the following map distances

 The interference among these genes is 0.5. Pure line breeding cross Gray body, Red eye, normal wings with black body, purple eye, vestigial wings. If heterozygous female for all loci were allowed test cross, the of progeny with gray body, purple eye and vestigial  wings out of 1400?
