Abstract
Out-of-season lambing in Icelandic sheep occurs at a significantly lower rate among white than among nonwhite (colored) ewes. This limitation on the length of the breeding season is ascribed to a previously unknown effect of the top dominant allele at the agouti locus, Awh, which produces the ordinary white color in sheep.
摘要
冰岛绵羊的非季节性产羔率在白色母羊中显著低于非白色（有色）母羊。繁殖季节长度的这种限制归因于刺豚鼠基因座上顶级显性等位基因Awh的一种先前未知的效应，该等位基因在绵羊中产生普通的白色。
