Paleontologist and embryologist J. G. M. "Hans" Thewissen noticed that the ear bone of Indohyus (a deer-like mammal) that had broken off in his lab was razor thin on one side and very thick on the other, making it unlike the ear bone of any other land mammal. Ultimately, this discovery shed light on the evolutionary history of whales. Which statements about whales and Indohyus are correct?

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.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
