A Case of Lethal Genes in the Horse

Abstract

THE only case of a lethal gene in the horse described hitherto was by Yamane¹ in Japan; it produced a blind large intestine, which caused colic and death among the new-born foals sired by one Percheron stallion. The following case, which I have observed in the well-known Polish stud of half-breed horses at Skrzydlów, p-Aurelów, near Czesto-chowa, is therefore of interest, because its explanation is analogous to that of Yamane's case mentioned above, although perhaps more complicated.
