In Box 3 of the above article, two equations were given incorrectly. In the second column of the table, last row, the correct equation is:

1 × F1 × p1 + (1 − π1) × p2 × F2)/F − π1

where F is the fertility rate for the total population.

In the third column, last row, the line should begin with a lower case g, to indicate simple covariance, and not G, which indicates the matrix. The correct equation should read:

g × Cov(F,SBP)/Var(SBP1) = h2 × Cov(F,SBP) = g × b
