Caprine plasma proteinase inhibitors--II. Genetic analysis.
1. Analysis of the inheritances of the variants of five caprine plasma proteinase inhibitor systems in families demonstrated a genetic control of codominant alleles at five loci. 2. The PIA, B, C, D and E proteins are controlled by four (PIA1,2,3,4), three (PIB1,4,0), three (PIC2,3,0), five (PID1,2,3,4,0) and two (PIE1,2) alleles respectively. Null alleles were postulated for the PIB, PIC and PID systems. 3. The frequencies of the alleles differed substantially between the Australian and Texan Angoras and Cashmere breeds of goats. 4. The combined exclusion probability for the five PI systems was as high as 0.82 in the Cashmere breed, indicating the potential of the proteinase inhibitor proteins for parentage control purposes.
