BMC Veterinary Research

Table 2 Segregation analysis – Parameter estimates, log-likelihood and AIC associated with the general autosomal mode of transmission and the general, dominant and recessive X-linked modes of transmission.

q₂: frequency of the risk allele 2; f₁₁, f₁₂, f₂₂: penetrances of genotypes 11, 12 and 22. No.: No. of independent parameters estimated = (no. of parameters in the model)-(no. of parameters that converged to a boundary); lnL: log-likelihood; AIC: Aikaike criterion (-2 lnL + 2 No). χ² (df): chi-squared test comparing the general X-linked model with the restricted X-linked models. P: associated p-value.
