les gènes les plus en aval specifient l'dentité des segments les plus antérieurs ou medians de l'embryon?

Thank you for using the Jiskha Homework Help Forum. Assuming you'd like a translation of the post, here you go:
The most downstream genes specify (error with "l'dentité" = probably L'identité?) the identity of segments the earliest or median of the embryo.
Now, if you are taking a biology class in French, I know nothing about science! If the translation is not what you needed, please give the entire context, or exactly where (for example) you found this!
