Model comparison using SEX-DETector on empirical datasets in Silene latifolia (with sex chromosomes) and S. vulgaris (without sex chromosomes) and simulated X/Y datasets with varying number of sex-linked contigs out of 10,000 simulated contigs. The best model is chosen as the one having the lowest BIC value (see “Materials and Methods” section and supplementary table S6, Supplementary Material online for details)
| Best model | number of sex-linked genes in the best model | ||
|---|---|---|---|
| Empirical datasets | Silene latifolia (X/Y system) | X/Y | 1357 |
| Silene vulgaris (no sex chromosomes) | Z/W | 0 | |
| Simulated datasets of 10,000 genes with different numbers of sex-linked genes (XY system) | 0 sex-linked genes | no sex chromosomes | 0 |
| 1 sex-linked gene | no sex chromosomes | 0 | |
| 10 sex-linked genes | X/Y | 16–57 | |
| 100 sex-linked genes | X/Y | 156–181 | |
| 500 sex-linked genes | X/Y | 592–624 | |
| 3000 sex-linked genes | X/Y | 3159–3200 |
