A flock of 10 random finches from a large population group flies to an island and there founds another large population as follows: In the first 5 generations, the population size remains 10. After this, the population size grows to a very large size N>>10000 and stays there for a 1000 generations. What fraction of the heterozygosity at an arbitrary neutral locus do you expect to be lost in passing through this bottleneck?
