[Problems in the genetics of stress. IV. A genetic analysis of the level of autonomic reactivity in emotional stress in rats].
A genetic analysis of hypertensive reactions under condition of emotional stress in three inbred strains of rats (Wistar, Sprague-Dowly and August) and their F1 reciprocal hybrids is carried out. Highly significant genotypic differences in the arterial pressure level during emotional stress and no genetic diversity in the basal state were found. Application of our own methos to genetic analysis of incomplete diallelic tables for Griffing's experimental design 1 (model 1) showed an existence of significant additive component of genetic variance in autonomic reactivity under the stress. The role of the stress as a factor of differentiation of the genetic structure of population is discussed.
