有性生殖還能夠促進(jìn)有利突變在種群中的傳播,。如果一個物種有兩個個體在不同的位點上發(fā)生了有利突變,在無性生殖的種群內(nèi),,這兩個突變體必將競爭,,直到一個消滅為止,無法同時保留這兩個有利的突變,。但在有性生殖的種群內(nèi),,通過交配與重組,可以使這兩個有利的突變同時進(jìn)入同一個體的基因組中,,并且同時在種群中傳播,。此外進(jìn)行有性生殖的物種其生活周期中都有二倍體的階段。二倍體的物種每有性生殖有性生殖一基因都有兩份,,有一份在機能上處于備用狀態(tài),。如果這個備用的基因發(fā)生突變,成為有新的功能的基因,,但此時新功能還是潛在的,。通過自發(fā)的重復(fù)和有性生殖中的遺傳重組,這個新基因可與原有基因先后排列,,這樣便產(chǎn)生一個新的基因,。二倍體物種可以用這樣的方法使其基因組不斷豐富。由于上述原因,,有性生殖加速了進(jìn)化的進(jìn)程,。在地球上生物進(jìn)化的余億年中,前余億年生命停留在無性生殖階段,,進(jìn)化緩慢,,后億年左右進(jìn)化速度明顯加快。除了地球環(huán)境的變化(例如含氧大氣的出現(xiàn)等)外,,有性生殖的發(fā)生與發(fā)展也是一個主要的原因,。
Sexual reproduction also promotes the spread of favorable mutations in the population. If there are two individuals in a species that have favorable mutations at different sites, in the population of asexual reproduction, the two mutants will compete until one is destroyed and the two favorable mutations cannot be retained at the same time. However, in the sexual reproduction population, the two favorable mutations can be simultaneously entered into the same individual's genome through mating and recombination, and they can also be transmitted in the population. In addition, sexual reproduction species have a diploid stage in their life cycle. Diploid species have two genes for each sexually reproductive gene, and one is functionally on standby. If this spare gene is mutated and becomes a gene with new functions, new functions are still potential at this time. Through spontaneous repetitive and genetic recombination in sexual reproduction, this new gene can be aligned with the original gene, which will generate a new gene. Diploid species can be used to enrich their genomes in this way. For the above reasons, sexual reproduction accelerates the evolutionary process. In the billions of years of biological evolution on Earth, the lives of the first billions of years ago have remained in the stage of asexual reproduction, and evolution has been slow. The rate of evolution has accelerated markedly after about one million years. In addition to changes in the global environment (such as the emergence of oxygen-containing atmospheres), the occurrence and development of sexual reproduction is also a major cause.
