Quizplus · Accepted Answer

The dihybrid cross did not show the expected 9:3:3:1 ratio because some of the alleles were linked, meaning they were located close together on the same chromosome and were inherited together more often than predicted by chance. This can result in certain phenotypes occurring more frequently than expected and others less frequently. Mitosis errors, sex-linked alleles, and polygenic inheritance would not explain the deviation from the expected ratio in this case.
