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?

Frequently asked questions

Can't I just make this for free with AI?

AI tools give you vast, general information. They don't know your course, your professor, or what actually gets asked in your exam. This document was written by a fellow student who understood the nuances of exactly this course and passed it. You get focused, curated study material, not a generic starting point you still have to rework.

Is this document still relevant for my course?

Every document shows the academic year, the linked textbook, and the institution, so you can check upfront whether it matches your course. Take a look at the free preview too to see if it fits.

What if the document isn't what I hoped?

No worries! If you change your mind within 14 days of purchase and have not downloaded the document yet, you can get your money back. Your purchase is completely risk-free.

Who am I buying these notes from?

Stuvia is a marketplace: you buy directly from the student who created the document. Stuvia handles payment securely and backs every purchase with the free exchange guarantee, so you never take on any risk.

Will I be stuck with a subscription?

No. You pay $13.44 once for this document and nothing more. No subscription, no auto-renewal, no fine print.
