The scenario that will decrease the genetic variation of a population is:
a population of birds suddenly decrease their frequency of sexual reproduction.
Decreased sexual reproduction can lead to less mixing of genetic material, resulting in reduced genetic variation over time as the gene pool becomes less diverse. In contrast, the other options either introduce new alleles or increase the potential for genetic recombination, which can contribute to greater genetic variation.
