Full description We analysed 3385 gene expression traits with non-zero among-line variance in a data set consisting of 41 mutation accumulation lines of Drosophila serrata. Frequent mutational covariance had previously been demonstrated in random 5-trait subsets of these 3385 traits (McGuigan et al 2014). Here we used the Bayesian sparse factor model modified from Runcie and Mukherjee (2013) to characterise the covariance among all 3385 traits simultaneously.
