A population of tribbles got on board two different starships and has been evolving apart for 6 months, or 20,000 generations. The effective population size for tribbles is 1*10. If the mutation rate for tribble DNA is 2.4*10-5/(bp gen), how many fixed differences would you expect to see between the two populations in a 1000 bp intron (assume the intron is evolving completely neutrally).

John Doe has two possible fathers. The DNA fragment sizes of John Doe, John Doe's mother, a possible fathers are as follows: John Doe's mother - 850 bp and 400 bp John Doe - 680 bp and 400 bp Possible father 1 - 680 bp and 500 bp Possible father 11 - 680 bp and 280 bp Which, If either of the two men could be John Doe’s father and why? A. both of the two men, because they and John Doe all have a 680 bp sized DNA fragment B. possible father II because both he and John Doe have a 680 bp sized DNA fragment C. possible father I because both he and John Doe have a 680 bp sized DNA fragment D. neither man, because neither has a 400 bp sized DNA fragment

By average, how many Sau3A (5’GATC3’) sites are there in a 10 kd DNA molecule? (1/4)^6 * 10,000 = 2.44140625 => 2.4 For the above 10 kb DNA, if you use Sau3A to do a complete digestion, you will only get a lot of small fragments ( 200~500 base pairs). What should I do if I want to get larger digested fragments (say 3 to 5 kb) Please answer asap and type your answer and do not copy from anywhere please
