It's 3 I had the same question.

Hope this Helps :)

answer; i believe the correct answer is (replication is not conservative);

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
