What was the key significance of this research finding?
A)A single gene is capable of controlling all aspects of male courtship.
B)Courtship is a complex series of events that is likely controlled by too many factors to investigate.
C)Courtship is not regulated by genetic influence at all.
D)Behavior in fruit flies is not transferable to other animals.

What happened when female fruit flies were given the male gene identified as “Fruitless”?
A)There was no significant response, it is male gender determined.
B)The female fruit flies died.
C)The females now behaved like males.
D)The males were no longer attracted to the females.

How did they know that the females had actually taken up the male gene into their chromosomes?
A)The females formed male genitalia
B)The females born grew much larger
C)They were unable to actually mark the genes, they just observed behavioral changes.
