A mutant allele of a new white spotting locus in the Norway rat is described, which is designated as head spot (hs). The allele is inherited as a recessive to normal. The expression is regularly manifested and has the form of a white sport of variable size in the middle of the forehead just above the eyes. A probable reoccurrence of blue dilution coat color is also reported. Tests for genetic linkage for hs indicate that it is independent of the agouti, dilute, and hooded loci.
本文描述了一种新的挪威大鼠白色斑点基因座的突变等位基因，命名为头部斑点（hs）。该等位基因相对于正常基因呈隐性遗传。其表现形式较为规律，表现为位于眼睛正上方前额中部大小不一的白色斑点。此外，还报道了蓝色稀释毛色可能再次出现的情况。对hs进行的遗传连锁测试表明，它与刺鼠色、稀释和头巾基因座无关。
