Loss of BBS2 changed the distribution of cilia length. Cilia length was measured by using light microscopy of H&E sections. Bbs2−/− and wild-type cilia showed the same average length: 4.1 μm. However, Bbs2−/− cilia exhibited a greater variation in length; variance for wild-type cilia (0.20) differed from Bbs2−/− cilia (1.22); P < 0.001, Levene test.
