  • Pearson product-moment correlations with asterisks indicating a difference from zero: *** P < 0.001; ** P < 0.01; * P < 0.05. These significance levels are not corrected for multiple tests. Along the diagonal (in italics) is the variance in bristle number associated with each genetic background/trait/sex combination. The first letter of each label corresponds to genetic background (W, whole X chromosome; B, fragments of the X chromosome including the ASC introgressed into a SAM background), the next two letters indicate the bristle trait measured (AB, abdominal bristle number; SB, sternopleural bristle number), and the last letter corresponds to the sex (M, male; F, female). The variance and covariance estimates among line means in this table include Ve and are thus not estimates of corresponding genetic parameters.
