The estimation of heritabilities and genetic correlations is based on the assumption that the trait distributions are normal. When the distributions are not normal it is advisable to transform the ...

Studies on Ipomopsis aggregata (Campbell, 1996) and P. viscosum (Galen, 1996), both Polemoniaceae, showed that field heritabilities of flower size are close to greenhouse estimates or are very high.

Only the three size variables were affected by sire identity. Heritabilities for locomotor performance, larval period, and size-independent performance were low (0.00-0.23) and not significant. Body ...
