Question 1

Briefly discuss the role of testosterone in sexual behavior of male rats.

Accepted Answer

Under normal circumstances, testosterone early in life organizes the male rat's nervous system so he has the potential to display male sexual behavior (mounting) in adulthood. Testosterone in adulthood is needed for the male to display sexual behavior.

Question 10

You are investigating the function of a pheromone receptor found in the vomeronasal organ (VNO) of mice.You hypothesize that when pheromones produced by a female mouse bind to the VNO receptors of a male mouse, the binding stimulates mating behavior.You test your hypothesis by doing a knockout experiment, silencing a gene needed for the VNO receptor to work.When you expose the knockout male mouse to a female mouse, the knockout mouse mates with the female.When you expose the same knockout male mouse to a male mouse, the knockout mouse tries to mate with the male.When you test a normal male mouse under the same situations, the male mates with the female, but reacts aggressively toward the male.What conclusion can you draw from these results?

Accepted Answer

A)  There is a single gene that controls mating behavior in male mice. 
B)  The VNO receptors are necessary for gender identification. 
C)  The VNO receptors are necessary for mating behavior. 
D)  The VNO receptors are necessary for sexual attraction.
