Generation of the bkbwg (for black eyes, big wings and naturally occurring N. giraulti visible markers in the region) introgression line and map of visible markers in the region. In the parental cross, Nasonia giraulti females were mated to Nasonia vitripennis peach males. In each backcross generation, heterozygous females, identified by visible markers (m) in the bkbwg region, were mated to Nasonia vitripennis peach males to further reduce the size of the introgression. To purebreed the line, heterozygous bkbwg/+v females were mated to bkbwg introgression males, and their homozygous bkbwg/bkbwg introgression female offspring were again mated to bkbwg introgression males in an attempt to produce an isogenic line. Inset is a map of the bkbwg region, including the location of visible markers ws1 (wing size 1), bl13 (blue 13), bk576 (black 576) and sww (shorter wider wings). Markers indicated with asterisks were used to track the bkbwg introgression. Distances between visible markers are shown in centiMorgans (cM).
