Abstract


This paper presents the method of formation of inbred lines of mice population of the Swiss strain. Aspects are presented with respect to prolificacy of inbred and non-inbred parental couples with different coefficients (25%, 37.5% and 50%). The statistical data show the major influence of the degree of homozygosity through identity of gene origin on the number of offspring. There were no reported hereditary malformations leading to the disappearance of individual carriers.
