Figure 7From: Complete association between a retroviral insertion in the tyrosinase gene and the recessive white mutation in chickensPrinciple of the PCR diagnostic test for the molecular identification of the insertional mutation in intron 4 of the chicken TYR gene. Two fragments may be obtained: 481 bp between Diag05-nor-up and Diagnostic05-dw for normal C*N allele, and 345 bp between Diag05-cc-up and Diagnostic05-dw for the C*C allele.Back to article page
