Fig. 3: A) Counts of synonymous (Ns) and nonsynonymous (Nn) mutations. The left panel shows comparisons of polymorphisms segregating within (EE, NN, TT) and fixed between (ExN, ExT, TxN) sexual species. The right panel shows averages (and s.d.) for private asexual SNPs per each hybrid genomotype. Letters correspond to haploid genomes as follows: E = C. elongatoides , N = C. tanaitica , T = C. taenia ; ‘x’ stands for interspecific comparison, so that e.g. ExT indicates comparison performed on C. elongatoides and C. taenia . B) Boxplots of observed heterozygosities within sexual and asexual individuals.
