Plot of the number of hits in the chicken genome per paired sequence from alligator for each BAC clone versus (x-axis) versus the distance between hits (y-axis). Each dot represents one BAC clone. For each BAC clone with a paired hit, the average lengths of the mapped hits on the chicken genome were computed. The y-axis scale is logarithmic. The plot is divided into three groups: clones with a large number of hits and a high intermarker distance for paired hits (black dots; lqPBH1); those with a small number of hits and a high intermarker distance for paired hits (green dots framed by a green square; lqPBH2); and finally those with a small number of hits and a small intermarker distance for paired hits ('high quality' paired hits, hqPBHs; red dots with encircling oval).
