Relationships of fatty acids between germline states and between sexes. (A, B) Within sex comparisons between flies with a germline or with no germline. (C, D) between sex comparisons of flies with a germline or with no germline. Each data point represents the between-replicate mean value (on a log2(x+1) scale; where x is the measured value) of a fatty acid. The red lines indicate the limits of 95% confidence intervals, based on bootstrap resampling methods .
