Question
If these conditions held constant – what would the expected heterozygosity be in the
population today (2018 to deal with a clean integer value for generations)?
1b. In 1884 the population had grown to 106 when disaster struck the island. Of the 19 adult men
on the island, 15 were in the same fishing boat that capsized, leaving only 4 adult men alive on
the island. These desperate times may have changed the sex ratio of the breeding population on
the island. Let’s say that now, each man fathered children with an average of 1.5 different
women (male:female ratio of 1:1.5). If we start back with a heterozygosity of 0.5 from this point,
given the effectivepopulation size on Tristan da Cunha, what is the expected heterozygosity in
the current population 7 generations later?
1c. The scenarios described in 1a and 1b are examples of which two evolutionary phenomena,
respectively?
