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.

Hox genes illustrate examples of orthologs, as they are conserved genes found in different species that evolved from a common ancestor (e.g., between mice and Drosophila). They also exemplify paralogs, where gene duplication within a species leads to new genes with novel functions. Lastly, some Hox genes that have lost all function are examples of pseudogenes.
