A Quantitative Genomic Approach for Analysis of Fitness and Stress Related Traits in a Drosophila melanogaster Model Population

Figure 1

Distribution of DGRP phenotypes for the five assayed traits. Each panel shows the mean phenotypic value (error bars indicate standard error) for each assayed DGRP line. Lines are ordered after increasing egg-to-adult viability at benign condition. (a) Egg-to-adult viability expressed in percentage at benign condition (circles) and at lightly stressful condition (squares). Black dots indicate the difference in viability between the two environments, genotype-by-environmental interaction (GxE); (b) time to heat knockdown (min); (c) Hsp70 expression; and (d) metabolic rate measured as CO₂ emission rate.
