In trying to understand the differences, a researcher analyzed data collected from 18 domesticated dogs and 10 wolves that had been raised by humans. Which data would be most useful to understand the genetic basis of this behavior?
A)The pedigree for the dogs and the geographic location from which the wolves came.
B)The number of chromosomes in wolves and dogs.
C)Differences in DNA sequences between the dogs and the wolves.
D)Examination of DNA from the ancient ancestor of dogs and wolves.
