A large population of wildflowers is genotyped at an autosomal locus with alleles C1 and C2. Researchers calculate allele frequencies from a representative sample of seeds and then compare expected genotype frequencies (p2p^2, 2pq2pq, q2q^2) to observed genotype frequencies in adult plants. Adults show a heterozygote deficit, while seed genotype frequencies are near Hardy-Weinberg. Field notes indicate that adult plants are spatially clustered by genotype due to microhabitat differences, and pollination occurs mostly among near neighbors. Hardy-Weinberg equilibrium assumes: (i) random mating, (ii) no selection, (iii) no mutation, (iv) no migration, and (v) large population size. Which factor most likely explains the deviation from expected genotype frequencies in adults?
