Perfusion patterns after FAL differ among CSS7, CSS17, and CXB-F1 relative to C57BL/6 and A/J strains. CSS7 and CSS17 are strains in which Chr 7 or 17 from the A/J strain has been substituted in place of the same chromosome in the C57BL/6 genome. A and B: CSS7 data suggest that a locus(loci) on Chr 7 has a major effect on the difference in perfusion between A/J and C57BL/6. C and D: CXB-F1 data show a trend toward overdominance of the C57BL/6 genome for recovery of perfusion. See Fig. 2 for additional analysis. Values are means ± SE.
