| No. genes AHP and BLP in both hybridscd | 9 | 6 | 1 | 0 |

This is the number of genes that are differentially expressed and pass the minimal signal and fold-change filtering requirements (as described in “Results”).
The number of differentially expressed genes that exhibit nonadditive expression was calculated based on a per-gene test for additive expression. The number in parentheses indicates the percentage of differentially expressed genes that exhibit nonadditive expression in both the BBM and MMB hybrids.
The number of genes that exhibit specific types of nonadditive expression patterns are reported. Only genes with nonadditive expression in both reciprocal hybrids are included. Values in bold indicate types of nonadditive expression that exhibit different prevalence in endosperm and vegetative tissues.
All genes in this category exhibit AHP expression in one hybrid and BLP expression in the other hybrid. No genes with AHP or BLP expression in both hybrids were observed.
The number reported here are the number of genes in which both hybrids exhibit nonadditive expression, but only one of the hybrids exhibits AHP or BLP expression. Note that this is smaller than the sum of values in Table II because some values in Table II represent genes that exhibit nonadditive expression in only one of the two hybrids.
