Question

I need help answering these questions. I'm not sure how to calculate Ne. 

Calculate effective population size (Ne) across the populations for islandA (use the main census table at the beginning of the test with 5 census years, and use the harmonic mean estimator for Ne). (A) 0<Ne < 20 (B) 20 < Ne < 40 (C) 40 <Ne < 60 (D) 60 <Ne < 80 Let us say that gene flow among the islands is uniform over the interval of study but varies across islands. Also, the islands have effective population sizes as indicated in the table, except you must enter your estimate for Ne for island A from problem 8. Ne Island A 0.59 Island B 112.6 0.46 Island C 517.9 0.02 Which island, based strictly on Ne, is most likely to experience fluctuations in allele frequencies due to random genetic drift? (A) island A (B) island B (C) island C Which island, based on the combined evidence of Ne and m, is most likely to drift away from the allele frequencies of the other islands? (A) island A (B) island B (C) island C

The Y locus has two alleles (Y = yellow, y = black; and Y> y, Y is dominant to y). The F locus controls fur length such: F-F = long fur F-F$ = medium fur F°F$ = short fur
