ABSTRACT
Natural populations of Daphnia are genetically heterogeneous with regard to phenotypic response to modification in the food quantity (a set of metric quantitative traits). In the majority of the traits, three genetically determined response types to the environmental factor studied have been detected arithmetic means decrease (R1), increase (R2) or remain constant (St) as a result of a decrease in the food quantity. This phenotypic response was shown to occur in the whole set of the metric traits studied, irrespective of physiological specialization. The problems of assessment of genetic population structure based on phenotypic response of the individuals reflected in quantitative traits are discussed.
