Statistical analysis of the number and length of outer segments between wild type and ift57 mutants.
A: At 60hpf, ift57 mutants showed no difference in length when compared to wild types. B-C: At 72hpf, the number of outer segments in ift57 mutant was reduced by 88% with no statistical difference in outer segment length. The length of the wild type outer segments did not significantly increase between 60 hpf and 72 hpf. D-E: At 96hpf, the number and length of outer segments was reduced by 90% and 38% respectively.
