[QUOTE="bigag03, post: 647513, member: 9247"] With Hereford cattle, I believe the 1970's article is accurate. The expression of scurs is controlled by the horn gene. The degree of expression is controlled by separate genes (these are the ones that are largely unkown). The problem comes when you insert Bos indicus influence. Problems with tracing the inheritance of horns/scurs in these cattle has always been blamed on the African Horn gene. That assumption is probably correct, but no one has been able to find this allusive gene yet or even completely understand its mode of inheritance. [/QUOTE]
