Table 4. Linkage of microsatellite repeat Z13833 in mok^m632 mapping panel

Linkage analysis of the CA microsatellite repeat Z13833, located about 4.2 cM from crx on chromosome 5, identified two alleles (designated A and B) in the mokm⁶³² mapping panel. All allele combinations (AA, AB and BB) are present in both homozygous mutant mokm⁶³² and their wild-type sibs. A maximum of 4 out of 8 homozygous mokm⁶³² mutants showed a single allele combination, corresponding to a 50% recombination rate. In contast, the predicted recombination rate between Z13833 and the closely linked crx gene is 4.2%. These results indicate that Z13833 and crx segregate independently from the mokm⁶³² mutant phenotype.
