remaining two loci (Oedu.T5 and Oedu.B0) at day 70. No temporal heterogeneity between stages was observed (Gh, P > 0.05) and data were therefore pooled. On pooled data, heterozygote excesses are significant at the experimentwise level ( = 0.0125) for thee loci (Oedu.O9, Oedu.T5, and Oedu.J12) and at the single test level for the fourth locus (Oedu.B0, P = 0.0246). The comparison of observed vs. expected MLH distributions corroborates the single-locus observations (Figure 1). An excess of higher multiheterozygous genotypes is observed, which is not significant at day 10 (G = 6.213, d.f. = 3, P = 0.10; without Oedu.J12: G = 5.987, d.f. = 2, P = 0.11; without Oedu.O9: G = 3.97, d.f. = 2, P = 0.26) but becomes significant at day 70 (G = 29.206, d.f. = 3, P = 2 x 10^-6; without OeduJ12: G = 19.68, d.f. = 2, P = 2 x 10^-4; without Oedu.O9: G = 20.4, d.f. = 2, P = 10^-5). No significant temporal heterogeneity was detected at the single locus level, whereas all loci exhibited an increase of the heterozygote excess D (Table 3). At the multilocus level, however, a significant temporal heterogeneity was found between MLH distributions at days 10 and 70 (Gh = 8.534, d.f. = 3, P = 0.036).

Cross C2: No significant heterozygote excess was observed at the youngest stage (day 1, Table 3). At days 10 and 70, Oedu.O9 exhibited significant heterozygote excesses at the experimentwise level ( = 0.0056), whereas D was significant only at the single-test level for Oedu.B0 (P = 0.0068 and P = 0.0246). No significant temporal heterogeneity was found for Oedu.O9 (Gh = 2.288, P > 0.05), and the Gp test exhibited a highly significant heterozygote excess on pooled data (Gp = 16.457, P = 5.1 x 10^-5). For Oedu.B0, a significant heterogeneity of heterozygote frequencies across stages was detected (Gh = 9.903, P = 0.0071). Because one may postulate that heterogeneity is due to homozygote mortality during the larval phase, partial heterogeneity tests were performed to determine which transition accounts for this. A temporal heterogeneity was detected between days 1 and 10 (Gh = 7.254, d.f. = 1, P = 0.0071) but not between days 10 and 70 (Gh = 0.108, d.f. = 1, P = 0.74). However, days 10–70 pooled data showed a highly significant heterozygote excess (Gp = 12.257, d.f. = 1, P = 0.0005). Figure 1 shows that excesses of multiheterozygous genotypes were already present at the end of the larval stage (day 10: G = 12.189, d.f. = 2, P = 0.0023, = 0.0167) and later (day 70: G = 8.159, d.f. = 2, P = 0.017, = 0.0167) but were not detected at the beginning of the free larval stage (day 1), for which no deviation from the expected MLH distribution is observed (G = 0.85, d.f. = 2, P = 0.6538.) No temporal heterogeneity was detected (Gh = 5.148, d.f. = 4, P = 0.27) using the three loci. Removing Oedu.T5, which perhaps behaved neutrally because homozygotes are not autozygotes, we obtained, however, a significant heterogeneity between days 1 and 10 two-locus MLH distributions (Gh = 8.888, concluding with, "d.f. = 2, P = 0.012) but not between days 10 and 70 (Gh = 0.718, d.f. = 2, P = 0.6983)."
