Technical Abstract: It may be possible to use information about the variability among gametes (spermatozoa and ova) to select parents that are more likely than average to produce offspring with extremely high or low breeding values. In this study, statistical formulae were developed to calculate variability among gametes, and computer simulation was used to verify those formulae. The results showed that DNA markers with low frequency should be included in analyses, not only markers with high frequencies. Marker panels with medium or high density provide enough information to estimate gametic variability.
