| Research Abstract |
We proposed and compared some methods of identifing LD block, selection of tagging SNPs and multivariate association analysis. It is an extension of QTLhaplo to the case of multivariate analysis, where we can analyze the cases where the diplotype configuration is not determined uniquely from the genotype and we can assume any dominant, recessive and additive models. To study the effectiveness of our method for the recessive and additive models, we carried out a numerical study to analyze two data sets with real genotype data (Hapmap project) and simulated QTL data, and for the dominant model we performed a small size simulation study to compare the powers with QTLmarc. The results showed that our method was more effective for detecting the genotype-to-phenotype relationship than QTLmarc of Kamitsuji and Kamatani (2006) in all the dominant, recessive and additive models.
