Question

1. Suppose you are studying a fruit fly’ s DNA and you discover a gene for antenna length on chromo- some

2. What word describes its location, and where would it be found in other fruit flies’ DNA?

Answer 1

Its location would be described as being at a particular locus on chromosome #2, perhaps in relation to the centromere or "on the short arm" of chromosome #2. If it is located on chromosome #2 in one fruit fly, that gene will also be on chromosome #2 of other fluit flies of the same species.
