Textbook Question
Chapter 6, Problem 23P
Replicating structures in DNA can be observed in the electron microscope. Regions being replicated appear as bubbles.
| a. | Assuming bidirectional replication, how many origins of replication are active in this DNA molecule? |
| b. | How many replication forks are present? |
| c. | Assuming that all replication forks move at the same speed, which origin of replication was activated last? |

From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
