The scenario that will decrease the genetic variation of a population is:
a population of birds suddenly decrease their frequency of sexual reproduction.
Reduced sexual reproduction can lead to less mixing of genetic material and can result in a population with lower genetic diversity over time. The other options either do not directly affect genetic variation or may increase it.
