title: Lack of evidence for segregation of a single dominant major gene as the cause of the difference in egg weight between two highly inbred lines of chickens.
abstract: Data on egg weight from experimental crosses with two inbred lines of chickens suggested evidence for segregation of a single dominant major gene. Because the data could not be transformed to satisfy normality and homoscedasticity conditions, the non-parametric test of Elston and the graphical approach used by Stolk et al. were applied. Due to a bad fit of the backcross B2 (P2×F1) and the F2 groups, both methods reject the hypothesis of a dominant major gene as the the only cause of the differences in egg weight between the six genetic groups involved.
