Figure 6: Quantitative profiling of central MUPs.

For each individual sample within each group (contact/allopatric, domesticus/musculus, male/female), each peak within the intact mass profile is expressed as a proportion of the total of all central MUP peaks in the profile. Individual values are present as black circles, superimposed on a box and whiskers plot (showing medians, 25–75% and furthest ranges). Statistical tests of differences in expression for each mass are shown in Tables 1 and 2. Sample sizes: domesticus male contact (n = 15), female contact (n = 30), male allopatric (n = 13), female allopatric (n = 8); musculus male contact (n = 19), female contact (n = 27), male allopatric (n = 13), female allopatric (n = 12).
