Hox genes are a family of transcription factors that regulate development throughout the animal kingdom. Studies of Hox genes in mice and Drosophila showed that many Hox genes are conserved between both species, and several Hox genes duplicated into new genes with novel functions within mice. Some Hox genes have even lost all function. Hox genes provide an example of which of the following? Check all that apply.
