#5. Developmental Biology

No, C. elegans does not have HOX genes
No, C. elegans has HOX genes but none of them are used during development
Yes, C. elegans has 4 clusters of HOX genes, just like mammals, that are required for specification of the identity of structures during embryogenesis
Yes, but only one HOX gene is required in the embryo; the others provide positional identity in the larva
