[Genetics and phenogenetics of hormonal characteristics of animals. VIII. Analysis of the variability of the corticosteroid function of the adrenal cortex of silver foxes during their domestication].
The contribution of genetic and environmental components in phenotype variety of corticosteroid adrenal function was studied in undomesticated and domesticated silver foxes during postnatal ontogenesis. The variation of basal and stress plasma corticosteroid level in animals aged 2, 4, 6, 8 months and in vitro secretion of the adrenal gland at the age 8 months was analysed. Significant genotype-depended variability was only demonstrated in undomesticated foxes under stress stimulation conditions. This phenomenon is manifested from the fourth month of life. However, significant genotype-depended variability was already revealed under basal conditions in domesticated foxes, on initial steps of postnatal ontogenesis. The peculiarities of genetic variability of adrenocortical function in foxes selected for domestication are discussed.
