You are a geneticist studying a mutation that results in dwarfism in a particular species of fish. You wish to determine whether the mutation is dominant or recessive, so you carry out several crosses with animals captured in the wild: Parent Phenotypes Progeny Phenotypes Cross #1 dwarf X dwarf 41 dwarf, 9 normal Cross #2 dwarf X normal 24 dwarf, 26 normal Cross #3 dwarf X normal 23 dwarf, 27 normala. Based on these results, is the dwarf mutation dominant, or recessive? What data led to that conclusion?
