已登记的安格斯、无角赫里福德和赫里福德公牛与未登记的安格斯和有角赫里福德母牛交配的结果与之前提出的假设大体一致，即4个独立基因座控制牛角和蹄角的遗传。讨论了对安格斯、无角赫里福德和赫里福德公牛与安格斯和有角赫里福德母犬交配产生的 830 个后代的观察结果。较高频率的毛痕、较大尺寸的毛痕和较高频率的凹凸与头球形状相关，按从扁平、圆形、尖峰和极尖峰的降序排列。划痕的存在和大小以及肿块的存在与头的形状并不独立。选择具有峰值投票的牛应该有助于减少产生的被污染的动物的百分比。
The results from mating registered Angus, polled Hereford and Hereford sires to nonregistered Angus and horned Hereford dams are in general agreement with the previously proposed hypothesis that 4 independent loci control the inheritance of horns and scurs in cattle. Observations on 830 progeny produced from mating Angus, polled Hereford and Hereford sires to Angus and horned Hereford dams were discussed. A higher frequency of scurs, scurs of larger size and a higher frequency of bumps were associated with shape of poll in descending order from flat, round, peaked and extremely peaked. Presence and size of scurs and presence of bumps were not independent of shape of poll. Selection of cattle with a peaked poll should contribute to a reduction in the percentage of scurred animals produced.
