Fig. 6.

Z gene expression. The same primers used in Fig. 4a were used to detect full-length Z transcripts from cDNA derived from the tissues of two TU or EKW individuals (different individuals than those used in Fig. 4). A negative control with no cDNA was included for each gene (−). Splice variants are labeled as in Fig. 4: one asterisk represents mhc1zca without an α3 domain (reading frame maintained), two asterisks represent mhc1zda with intronic sequence between the leader and α1 domains (reading frame not maintained), and four asterisks represent mhc1zka with intronic sequence between the α2 and α3 domains (reading frame not maintained)
