ONLY PART B :
a)Black bears on the island of Newfoundland have a microsatellite heterozygosity of 0.36 while that of the population on the Canadian mainland is 0.792. Calculate the mean inbreeding coefficient of the Newfoundland population assuming that the mainland population is completely outbred and acted as the source of the island population
F = (0.792 - 0.36 ) / 0.792
b)Island populations of species endemic to islands (found only their) have higher mean inbreeding coefficients (F) than island populations of non-endemic species. Populations of island endemics are also more prone to extinction than populations of non-endemics. What does this tell you about inbreeding? Explain why this comparison tells you more than comparing F and extinction rates of island endemics with related taxa on the mainland?
