Question 1
In dog populations, the coat color pattern gene E can be any one of 5 alleles. This is an example of:
◦ codominance.
◦ partial dominance.
◦ silent mutations.
◦ polymorphism.
◦ leaky mutations.
Question 2
In the density labeling experiment to study DNA replication, parental DNA in the cell was labeled with a high-density isotope and, after one or more generations of growth, subjected to density gradient centrifugation. Though DNA replication is semiconservative, consider what would happen if it is actually conservative. Which of the following populations of molecules would be detected after the first generation of replication?
◦ The light density population only
◦ The hybrid density population only
◦ The heavy density population only
◦ Both the light and heavy density populations
◦ Both the light and hybrid density populations
