[Studies in chicken genetics: commemorating the 120th anniversary of the outstanding Soviet geneticist A. S. Serebrovsky (1892-1948)].

The paper highlights the research of A. S. Serebrovsky in chicken genetics, including gene mapping and inheritance of morphological traits. Genetic formulas for several breeds are presented. The data of genetic surveys for local chicken populations from 23 regions of the former Soviet Union are also reviewed. The personal data of the authors on the morphotypological characteristics of different chicken breeds are given and discussed.
