hi. this is what i understand of it, but i am not 100%

Sonic gene-- produced at base of limbs @ zone of polarzing acitivity
- responible for -- # and placement of limbs , eyes and other structures - along the body.

Wnt gene-- prod. at apical ectodermal ridge (distal end of developing limbs)
-- responsible for - the organization of that limb ant/post'rly - like which sides the palm on etc.

FGF gene - respon. for lengthening of limbs
homebox gene -- segmental organization - like where the eyes are supposed to form and where the thoraic is supposed 2 form.

- if someone could confirm or edit this would be great. thx
