A  aThe inheritance of horns in the goat.h[electronic resource]  c1925  aAbstract: An examination of the Herd Book of the Brotish Goat Society and of privately kept herd records provided strong support for the contention taht, as in cattle, the polled and the horned conditions in the goat constitute a Mendelian pair of characters, polled being dominant. The data were too meagre to warrant any attempt to interpret the significance of scurs. Attention is called to the interesting fact that in this matter of horn inheritance the goat apparently resembles the ox rather that the sheep. THE earliest reference in scientific literature to this subject seems to be that of Batesoa and Sauaders (1902) who suggested that "the fact that the hornless breeds of goats still give sonic horned offspring is probably referable to the same cause (heterozygosity). The point is, of course, not certain, but from the analogy of cattle we may anticipate thai, the hornless form is dominant." IIowever, when an analysis of the Herd Book of the British Goat Society was made by Davies (1912), it was found that among the 2500 entries there were 32 instances of two horned parents yielding a hornless kid. These cases, of course, cannot be accommodated by the suggestion that the, polled condition, in its relation to the horned, is one of simple dominance. In this paper the analysis of the Herd Book is brought up to date in a further endeavour to disclose the genetic relationship of these two characters.  aAnimal genetics  aGoats  aHorns  aBode  aCaprino  aChifre  aMelhoramento genético animal  aBillygoats  aHerdabilidade  aMale animals1 aCREW, F.
