SECTION A
Answer all questions in this section.
01
The Hawaiian Islands have the most diverse collection of Drosophilid flies
in the world with approximately 800 different species having been
identified.
All of the species have been traced back to a single common ancestor from
mainland USA that colonised the islands millions of years ago. It is
hypothesised that this could have been a single fertilised female blown
across in a storm or trapped in a piece of fruit stuck to a bird.
a) What is a gene pool?
