Abstract
Numerical iterations have shown that periodic haploid two-locus selection with nonoverlapping generations can produce large-scale cyclical behavior with a period differing significantly from the environmental period. Among other types, we observed slowly damping oscillations with very long periods, stable T-cycles with a length containing several environmental periods, and chaotic-like dynamics. Possible biological implications are discussed.
摘要
数值迭代表明，具有不重叠世代的周期性单倍体双位点选择可以产生大规模的周期性行为，其周期与环境周期有显著差异。在其他类型中，我们观察到具有很长周期的缓慢衰减振荡、长度包含几个环境周期的稳定T周期以及类似混沌的动力学。文中讨论了可能的生物学意义。
