Summary:
The aim of this study was to estimate the genetic parameters associated to the environmental variability
of the following traits in mice: weight at 21 days, weight at 42 days and weight gain between
21 and 42 days. Data were obtained from a experimental mice population selected during 17 generation
for increase of adult weight and included 4896 males. Data were analysed using Bayesian procedures
after fitting two different models: that of homogeneous variances and that of heterogeneous
variances. Genetic correlation between the analysed traits and their variability was always negative
ranking from -0.22 to -0.61. Results allow concluding that there is a possible genetic component
affecting the analysed traits thus making possible its reduction by selection.
