Analysis of the signatures of positive selection in the genome of GZB compared to YBG. a Distribution of θπ ratios (θπ, YBG/θπ, GZB) and FST values, which are calculated in 100 kb windows sliding in 10 kb steps. Data points located to the right of the vertical dashed lines, respectively (corresponding to the 1% right tail of the empirical θπ ratio distribution, where the θπ ratio is 2.274), and above the horizontal dashed line (the 1% right tail of the empirical FST distribution, where FST is 0.3506) were identified as selected regions for GZB (blue points). b Manhattan plot of selective sweeps using θπ ratio in GZB vs. YBG. Solid blue line represented the threshold of the top 1% θπ ratios. c Manhattan plot of selective sweeps using FST in GZB vs. YBG. Solid blue line represented the threshold of the top 1% FST values. d-e Example of genes with strong selective sweep signals in GZB. θπ ratio and FST values are plotted using a 10 kb sliding window. Gray rectangle regions were termed as regions with strong selective sweep signals for GZB. The boundaries of ENSCHIG00000006864 and METTL15 genes are marked in red
