Which would least likely result from a chromosomal change?
a) death of the cell or organism
b) no effect on the cell or organism

d) change to the phenotype of the organism

I am pretty sure that the result which would least likely occur from a chromosomal change is being shown in the second option represented above : B) no effect on the cell or organism. I choose this one because chromosomes always affect every part of the body. Do hope you still need the answer because this one will definitely help you!
