Forty new genomes shed light on sexual reproduction and the origin of tetraploidy in Microsporidia

Age distributions of duplicate gene pairs.
Histograms showing synonymous divergence (Ks) distributions for candidate paralogous BUSCO gene pairs from representative diploid genomes. No evidence of recent rediploidisation events is seen, as there are no peaks against a background exponentially-decaying distribution coming from small-scale gene duplication events. The y-axis is highly variable due to different BUSCO gene family expansions occurring in different lineages, yielding larger counts of possible paralogous gene pairs. wgd was used to identify paralogous genes in every genome and compute Ks values [104].

The figure was generated using Matplotlib [92], and manually annotated using InkScape (version 1.2.2).
