  • Number of observations and unique genotypes available for analysis are given in brackets in the column Trait. Narrow sense heritability (h2) of direct genotypic effect is given. Competition form is given bracketed with the maximum distance (Dist) covered and/or parameter values. Chi-square statistic, calculated from the log likelihood values of the Base and Model 1 or 2*, is given with p-value (in brackets). Table S5 in File S1 is an elaborated version of this table.
