Abstract
Restriction fragment length polymorphism (RFLP) analyses of swine leukocyte antigen (SLA) class I and class II genes from Swiss Large White and American Hampshire families were performed using porcine DNA probes. Class I and class II RFLPs associated with the serologically‐defined haplotypes SLA H1, H8, H16 and H24 and with serotypes SLA 15, 16; SLA 14; and SLA 6, SB 19, were identified. Seven allelic class I RFLP patterns were observed. For genes in the SLA class II region, six allelic RFLP patterns of DQA and DQB; five allelic RFLP patterns of DRA; and seven allelic RFLP patterns of DRB were observed. The serologically‐defined H8 haplotype was subtyped based on differences in class II RFLPs.
