A small, isolated lizard population on a desert outcrop has allele TT at frequency 0.52 at a neutral locus. Over 20 generations, with no immigration and no detected genotype differences in survival or reproduction, p(T)p(T) fluctuates unpredictably between 0.30 and 0.70. The census population size remains around 80 adults each generation. Which factor most directly explains these allele frequency fluctuations?
