The widths of all six molars were examined in coisogenic house mice of strain 129/J to determine whether they were being influenced by chinchilla alleles at the albino locus. Although genotype differences did not reach formal significance in the analyses of variance for any molar (or body weight) in either sex, the molar means for chinchilla homozygotes were less than those for the albinos in 11 of the 12, and for heterozygotes in 12 of 12 combinations. The difference between the two homozygous genotypes within each molar and sex averaged 0.25 standard deviations. Static allometry coefficients were calculated for each genotype and sex from partial regressions of the logarithms of each of the molars on the logarithms of the cube root of body weight, adjustment being made for the effects of litter size and the day the litter was born. These coefficients all were low in magnitude (negative allometry), and multivariate analyses of covariance showed that they differed significantly among genotypes in males, but not in females.
在129/J品系的同基因家鼠中检查了所有六颗臼齿的宽度，以确定它们是否受到白化位点上青紫蓝等位基因的影响。尽管在对任何一颗臼齿（或体重）的方差分析中，基因型差异在两性中均未达到显著水平，但在12种组合中的11种中，青紫蓝纯合子的臼齿均值低于白化小鼠，在12种组合中的12种中，杂合子的臼齿均值也低于白化小鼠。每颗臼齿和性别中两种纯合基因型之间的差异平均为0.25个标准差。根据每颗臼齿对数与体重立方根对数的偏回归，计算了每种基因型和性别的静态异速生长系数，并对窝仔数和窝仔出生日的影响进行了校正。这些系数的大小都很低（负异速生长），多变量协方差分析表明，它们在雄性基因型之间有显著差异，但在雌性中没有。
