From: Experimental determination of evolutionary barriers to horizontal gene transfer

DFE of 44 newly transferred S. Typhimurium orthologs expressed in E. coli. On the x-axis, genes are sorted by their fitness effects (s). Error bars indicate the 95% CI of the selection coefficients from 32 replicate measurements for each gene. Empty circles represent the 5 genes with effects not significantly different from zero. Embedded plot gives the histogram representation of the same data
