Extended Data Fig. 3: Estimation of introgressions among the six groups of Brassica juncea.
From: Genomic insights into the origin, domestication and diversification of Brassica juncea

a, Treemix analysis. Migration arrows are colored according to their weight. Horizontal branch length is proportional to the amount of genetic drift that has occurred on the branch. Scale bar shows ten times the average standard error of the entries in the sample covariance matrix. b, f-branch values. c, fd values from G2 to G4. The center lines in box plots indicate the median values, and the bottom and top edges of the box indicate the 25th and 75th percentiles, respectively. Whiskers extend to data no more than 1.5 times the interquartile range. p-value was calculated using two-sided t-test.
