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?

 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.
