| Research Abstract |
In this study, a computing procedure and system for genetic evaluation of resource animals using the chromosome segment model was considered. Those for the genetic evaluation using a large amount of SNP data were also investigated considering several approaches. Using simulated and actual data of hetero-stock mice and cattle, validities of those computing procedures were examined. Based on the theory and simulation study, the genetic evaluation of resource animals using the chromosome segment model was shown to be useful. Bayesian methods fitting SNP effects appeared to be relatively accurate and promising, in terms of estimation of total genetic merit, compared with the mixed model method using the polygene model.
