Homeotic genes were first discovered in Drosophila fruit flies. They are genes that control the development and differentiation of tissues and organs in embryos. These genes are highly conserved in evolution. Alteration of these genes results in alterations in the ​development of limbs and tissues and is often so catastrophic that offspring does not survive.

Which of the following BEST describes the role of homeotic genes?


These are genes that direct the development of tissues and organs in the embryo.


These genes direct the processes of cell division within the embryo.


These genes direct proteins to bind to RNA, increasing the expression of certain genes at certain times.


These genes were first discovered in prokaryotes and because they are highly conserved were passed down to eukaryotic cells.
