The possibility of evolutionary explanation of dominance relations for alleles in selective-neutral rec-loci was explored by means of numerical experiments. It was shown that selection for two-loci fitness system causing the secondary (induced) selection for the rec-system, results in changing the allele frequency of the second-level modificator gene controlling the dominance relations in the rec-locus. The dominance of rec-allele, providing the favourable for the given conditions level of crossing-over between selected fitness loci, is established, due to these changes. It was found that the neutral dominance modificator can influence the dynamics of the whole system.
通过数值实验探讨了对选择性中性rec基因座中等位基因优势关系进行进化解释的可能性。结果表明,对双基因座适合度系统的选择会导致对rec系统的二级(诱导)选择,从而改变控制rec基因座中优势关系的二级修饰基因的等位基因频率。由于这些变化,rec等位基因的优势得以确立,这种优势为所选适合度基因座之间的交叉提供了在给定条件下有利的水平。研究发现,中性优势修饰因子可影响整个系统的动态变化。
