Signatures of Diversifying Selection in European Pig Breeds
Figure 2
Patterns of genetic variation associated with pig ear phenotypes.
A. Genomic distribution of signatures of diversifying selection as measured by genetic differentiation. The top panel shows prick-eared breeds against flat-eared breeds. The second panel shows prick-eared breeds against intermediate-eared breeds. The third panel shows intermediate-eared breeds against flat-eared breeds. B. Variation in breed allele frequencies of SNPs at the candidate region for ear morphology on SSC5. The top panel shows the allele frequencies for each of the European breeds (colour coded by the ear morphology class to which they belong) and Meishan. The second panel shows the positions of biologically interesting genes in that region.
