As a direct consequence of sex, organisms undergo a haploid and a diploid stage during their life cycle. Although the relative duration of haploid and diploid phases varies greatly among taxa, the diploid phase is more conspicuous in all higher organisms. Therefore it is widely believed that diploidy offers more evoutionary possibilities1–3 and is thus nearly always selected for. We have now performed computer simulations to investigate one possible advantage of diploidy, that is, protection… CONTINUE READING
