Problem: A scientist study the role of PITX1 in the development of hard tissues in the Antler Eel finds that PITX1 is expressed in the spines of the fins and that an almost identical gene is expressed in the antlers. This second gene probably arose due toa. a change in a regulatory gene  b. a change in a coding gene  c. gene duplicationd. changes in histone acetylation  e.  changes in bicoid
