Penna性衰老模型中的配子识别和互补单倍型
Gamete recognition and complementary haplotypes in sexual Penna ageing model
摘要：
在模拟二倍体个体的有性生殖中，我们介绍了雌性单倍体配子识别基因组中的一个特定等位基因作为雄性单倍体配子的标记。它们与受精卵融合，最好是与具有不同标记的雄配子融合。这种配子识别在低重组率下增强了模拟二倍体个体中互补位串的优势。因此，在罕见的重组中，位串进化为互补的;而在重组率高于约0.1的情况下，它们在达尔文纯化选择下进化，只有很少的位发生突变。
英文摘要：
In simulations of sexual reproduction with diploid individuals, we introduce that female haploid gametes recognize one specific allele of the genomes as a marker of the male haploid gametes. They fuse to zygotes preferrably with male gametes having a different marker than their own. This gamete recognition enhances the advantage of complementary bit-strings in the simulated diploid individuals, at low recombination rates. Thus with rare recombinations the bit-string evolve to be complementary; with recombination rate above about 0.1 instead they evolve under Darwinian purification selection, with few bits mutated.
