1. On p. 922 (middle of 2nd column), Omega is defined as 2*phi*sigma^2_a + Delta^7*sigma^2_d. However, the Omega used on p. 923 and subsequently is the above plus I*sigma^2_e. The easiest fix would be to replace the Omega on p. 922 with a capital Sigma, and then on p. 923 define Omega to be Sigma + I*sigma^2_e. 2. This is not an error or typo, just a clarification: on p. 9, the diagonal of the matrix bold capital Phi has ith element (1+rho_i)/2, which is just the kinship coefficient of individual i with himself, where rho_i is the inbreeding coefficient of the ith individual. Similarly, the diagonal of the matrix bold capital Delta has ith element 1-rho_i.
