句子大意是,对于hp的studies显示出对s-f和c-f species的bias,于是这些studies就将其mix up以inflating其species frequency. 接着后面来了一个nevertheless说明这个mixture对于species frequency没有起到inflating的作用,原因就是其数量不__.
如果选not trivial的话就成了large number of mixed species,但这里的因果关系显然是mixed species determine the inflating of the frequency of species(见thus inflating the frequency of species using a mixed mating system),于是the lacking mixed species就导致了inflating的失败.
relevant在这里是significant的意思. not relevant=not significant=low in numbers. 选D.
