Genomic information, mainly SNP-genotype data, is utilized in genome-wide association studies (GWAS), genomic selection methods and population genetics analyses. We have used Porcine 60K SNP chip data of Finnish pig breeds to investigate genetic basis of pork quality, lethal haplotypes and effective population size. Currently we exploit gene expression and targeted sequencing to validate our previously found candidate genes for pork quality. This is done in collaboration with the research group at the University of Bologna. In the Ayrshire dairy cattle, imputed 50K SNP-genotypes of over 10,000 Finnish cows have been used for estimating levels of genomic inbreeding.
