Identification of the origin of triploidy by HLA markers.
HLA-A and HLA-B markers have been determined in fibroblasts grown from tissues of triploid conceptuses and have been tested in the parents. Informative data on the origin of triploidy were obtained in eight cases: diandry I or dispermy in 4 cases, diandry II or dispermy in 2, digyny I or II in 2. This confirms that triploidy involved more frequently two sets of paternal chromosomes.
