P -values (-log10(P-value)) for SNP effects on chromosomes with significant or suggestive SNP. The threshold value for significant association is indicated by the blue horizontal line and that for suggestive association by the red horizontal line. 1: SSC9 and total number of piglets born in first parity (TNB1); 2: SSC9 and total number of piglets born in later parities (TNB2); 3: SSC1 and number of stillborn piglets in later parities (NSB2); 4: SSC9 and piglet mortality between birth and weaning in first parity (PM1); 5: SSC7 and piglet mortality between birth and weaning in later parities (PM2); 6: SSC9 and PM2; 7: SSC4 and first farrowing interval (FFI); 8: SSC1 and second farrowing interval (SFI).
