Abstract

Defining multiple base populations for a genetic evaluation is subjective and there is generally no feedback on the suitability of the defined base populations prior to model validation. We present a number of statistics that can be used to evaluate defined base populations. Application of these statistics to one simulated and two practical datasets showed that in practical datasets the number of base animals per base population was in one case very low. In many cases the available genotype information for different base populations was coming from exactly the same genotyped animals. Both issues are likely to complicate genomic evaluation. A tool to estimate these statistics is available in the MiXBLUP software suite.
