遗传学家认识到的第一个因素是agglutinin，其中五个等位基因现在是可用的。这些在许多等位基因系列中观察到的简单线性顺序中不相关，但表现出相当特殊的特征。四个等位基因与可行的纯合子产生表型效应，并显示显性关系，类似于两个紧密连锁的因素。优势关系如下（图2）：
The first of these factors to be recognised by geneticists is that for agouti, of which five alleles are now available. These are not related in the simple linear order observable in many allelic series, but exhibit rather exceptional features. The four alleles with viable homozygotes produce phenotypic effects, and display dominance relationships, analogous to two closely-linked factors. The dominance relationships are indicated below (fig. 2):—
