种族可以根据它们可以感染宿主种群的哪些子集来分类。一个例子如图1所示。如果发生感染，一个给定的宿主菌株和寄生虫小种被认为是相容的；亲和性由+符号2表示。寄生虫的小种1可以感染宿主菌株A，但不能感染B；相反，寄生虫的小种2与宿主菌株B相容，但不能与宿主菌株A相容。宿主菌株之间的杂交表明，菌株A携带一个基因RA，该基因赋予对寄生虫第一小种的显性抗性，而菌株B携带第二个基因RB，用于对小种2的抗性。这些基因在这里被证明是独立的，但在许多情况下是等位的。从这个例子可以得出三个结论。首先，宿主对寄生虫的抵抗力是有条件的，因为它取决于寄生虫的基因。将寄主种群的成员归类为抗性或敏感的分类过于简单化；假以时日，几乎肯定会出现新的小种。
Races can be classified according to which subsets of the host population they can infect. An example is shown in Fig. 1. A given host strain and parasite race are said to be compatible if infection occurs; compatibility is designated by a+ sign 2. Race 1 of the parasite can infect host strain A, but not B; in contrast, race 2 of the parasite is compatible with host strain B, but not A. Crosses between the host strains reveal that strain A carries a gene RA that confers dominant resistance to race 1 of the parasite, while strain B carries a second gene RB for resistance to race 2. These genes are shown here as being independent, but are in many cases allelic.Three conclusions can be drawn from this example. First, host resistance to the parasite is conditional, since it depends on the genotype of the parasite. The classification of members of the host population as either resistant or susceptible is overly simplistic; given time, new races are almost certain to appear.
