Description The file, measurement_data.csv, includes the measured values of the all individuals we used in our quantitative genetic analyses. The first column heading, "Population", indicates used populations in the quantitative genetics. “P1” is D. b. capito; “P2” is D. b. fortunei; “F1” is hybrids produced by crossing D. b. capito and D. b. fortunei; “B1” is backcross population to D. b. capito and “B2” is a backcross population to D. b. fortunei. The second column heading, “HW”, indicate head width. The third, “HL”, indicate head length. The forth, “TW”, indicate thorax width. The fifth, “TL”, indicate thorax length. The sixth, “EW”, indicate elytron width. The seventh, “EL”, indicate elytron length. These measurement values have the unit of millimeter. The last column heading, “Randomly chosen 48 individuals”, indicate the individuals used to determine the eigenvector for the principle component analysis. To remove bias caused by differences in sample size between parent, F1, and backcross populations and to determine PC axes meaningful for quantitative genetic analysis, we first randomly chose 48 individuals from each population (i.e., 240 individuals in total). “TRUE” indicates the chosen individuals. By using the determined eigenvector, we calculated the principle component scores of the other 268 individuals as well as randomly chosen 240 individuals.
