Biased Gene Content of the Non-organelle-targeted Genes Across the Subgenomes of Five Allotetraploid Angiosperms.
| Speciesa | Diploid Paternal Model | Paternal Subgenome | Maternal Subgenome | Diploid Maternal Model | r PAT − rMAT (95% CI)b,c | Binomial test p-value |
|---|---|---|---|---|---|---|

a
Tobacco was excluded from this analysis because its subgenomes cannot be easily disentangled based on the chromosome number.
b
r PAT refers to the ratio of genes found in the paternal subgenome relative to the paternal diploid model, and rMAT refers to the ratio of genes found in the maternal subgenome relative to the maternal diploid model.
c
95% CIs were inferred from the Exact binomial test in the R stats package, following Clopper and Pearson (1934).
