CORRIGENDUM
AbstractAn error appeared in the legend for Figure 17, Page 147 of the article by Blackwell et al., "A Hydrocephalic Lethal in Hereford Cattle," which appeared in the May-June 1959 issue of the Journal. The legend as it should read is as follows: Pedigree showing introduction of lethal gene through sire A and typical matings that produced hycirocephalic calves. Old line mates omitted for simplicity. Squares represent males; circles, females; diamond, sex unknown. Solid shaded symbols represent hydrocephalic calves; solid half-shaded symbols represent parents of hydrocephalic calves cross-hatched half-shaded symbols represent animals incriminated as carriers through their descendants. The coefficients of relationship between 19 lethals and bulls A and D averaged 21 percent and 38 percent, respectively. The coefficients of relationship among the 19 lethals averaged 26 percent and their inbreeding coefficients averaged 11.7 percent.
