The nature of variability of quantitative morphometrical characters was studied in larvae of two local populations of Argas (Argas) polonicus Siuda, Hoogstraal, Clifford et Wassef, 1979 collected in Czechoslovakia and Poland. Statistically significant differences in five quantitative characters studied, in which the larvae of both wild populations differed from one another, disappeared during three generations of laboratory rearing. The variability of these characters was lower in laboratory populations than in field collected ticks. The results of hybridization experiments and analysis of variability of larvae of individual populations and parental pairs suggest that rather adaptive than genetic variation is involved. The genetic component of the variation is inferior and is expressed probably by dominant relations between alleles of the same locus, or by different types of non-allelic interactions.
对1979年在捷克斯洛伐克和波兰采集的波氏锐缘蜱（Argas (Argas) polonicus Siuda、Hoogstraal、Clifford及Wassef）两个本地种群的幼虫，研究了其数量形态特征的变异性质。在研究的五个数量特征中，两个野生种群的幼虫存在统计学上的显著差异，但在实验室饲养三代后这些差异消失了。这些特征在实验室种群中的变异性低于野外采集的蜱。杂交实验以及对各个种群和亲子对幼虫变异性的分析结果表明，涉及的变异更可能是适应性变异而非遗传变异。变异的遗传成分较低，可能由同一基因座等位基因之间的显性关系或不同类型的非等位基因相互作用所表达。
