Hox genes are genes that play an important role during embryonic development. They are
regulated genes, they in turn regulate other genes during development[a]. Hox genes can be
found in both vertebrates and
One way new genes come about is through a type of mutation known as gene duplication.
When a cell duplicates, sections of DNA are often copied by accident onto the same or a
different chromosome; but often these duplicated genes h

Epistatic Interactions are processes where two or more genes undergo epistasis. Epistasis is the process
where to genes rely on one another to produce a phenotype, by having one mask another.(a).
Contrary to genes in epistatic
