[Genetic control of the serotonin content in the blood of mice].

The Griffing's method of diallel analysis and hybridological analysis were used to study inheritance of serotonin level in blood in mice. Effects of general and specific combining ability proved to be highly significant, the former being more pronounced. Results of hybridological analysis allowed to suggest a simple genetic control involving a small number of genes. A conclusion is drawn that the level of serotonin was mainly determined by additive affects of genes.
