Previously unreported white spotting was found in two subspecies of the California vole, Microtus californicus. The pattern of spots on the ventral coat of the animals differs between the subspecies, and there is variation in the expressivity of the white spots. Expression of white spotting is greatly reduced by the epistatic action of another coat colour gene, the recessive buffy (bf). The incidence of white spotting, its variation in expression, and its inheritance were investigated in this study. The reproductive performance of white spotted voles were also analysed, and effects of fertility and litter size were found associated with the trait.
在加利福尼亚田鼠（Microtus californicus）的两个亚种中发现了此前未报道过的白色斑点。两个亚种动物腹部皮毛上的斑点图案不同，白色斑点的表现度也存在差异。另一个毛色基因——隐性的浅黄色（bf）的上位作用极大地降低了白色斑点的表现。本研究对白色斑点的发生率、其表现的变化及其遗传进行了调查。还分析了有白色斑点田鼠的繁殖性能，发现生育力和窝仔数的影响与该性状有关。
