How is it that a mutation in the Ptx1 can allow it to stop being active in the pelvic area, but not in the other tissues of stickleback fish? Group of answer choices A- The mutation is in the GENETIC SWITCH that turns ON/OFF the genes that lead to PRESENCE/ABSENCE only of pelvic fins.   B- The mutation is in the GENE that makes the materials that build only the pelvic fins.
