The phenotypic mean of all the RILs were similar to the mid-parent values for all remaining traits that were measured.
Using these line values, significance of skew about the mid-parent values for each RIL family was estimated by a modified two-sided D'Agostino Pearson test (D'Agostino 1970).
To assess the proportions of statistically additive and non-additive expression patterns in the hybrids, we conducted t-tests of the hybrid expression values versus the inbred mid-parent values for all DE genes.
The heritability of this quantity was investigated by regressing the child values against the mean of the parent values in HapMap trios for which microarray data were available for the offspring and both parents (56 trios).
The average value of the RILs was close to the mid-parent value for several traits, either agronomic or related to resistance.
Following the same reasoning, the decrease in the E p/Ē t ratio in SN relative to the mid-parent value for TC-specific probes is evidence of down-regulation of TC-type expression (Fig. 3C), while an increase of SN E p/Ē t ratio relative to the mid-parent value suggests an increase in TC-type expression (Fig. 3A).
We assessed the heritability of splicing index by estimating the slope of the correlation of child SI with the mean of parent SI values for 46 two-parent and child trios, for which exon array data were available for the complete trio.
We used the experimentally measured mid-parent values (MPVs) for each parental species combination which was generated by mixing the RNAs of parental lines (T. turgidum and Ae. tauschii) at a ratio of 2 1 to exclude this confounding factor.
Despite a similar range of parents and progeny across families, transgressive segregation was present in all families and significantly asymmetric about mid-parent values in 9 families for PHT, suggesting a role for epistasis.
The findings revealed that both parents and their children value education for instrumental purposes and, while age and employment status made no difference to the parents' value of education, there was a statistically significant difference in value of education between parents with children attending different school types.
