Assume a cross is made between AaBband aabb plants and that the offspring occur in the following numbers: 106 AaBb, 48Aabb, 52 aaBb, 94 aabb. These resultsare consistent with the following circumstance:
sex-linkedinheritance with 30% crossing over
linkage with 50%crossing over
linkage withapproximately 33 mu between the two gene loci
100%recombination
