Figure 2From: Multigenic nature of the mouse pulmonary adenoma progression 1locusMultiplicity of lung tumors larger than 2 mm in diameter (N2lung) in (SWR/J x CXBN)F1 mice treated with a single dose of urethane. For each of the 13 F1 groups derived from various CXBN lines (x-axis), dots represent mean N2lung values and bars represent S.E. of the mean. Number of mice per F1 group ranged from 20 to 35.Back to article page
