Description
1. INTRODUCTION Why sexual reproduction? This question is of interest not only to biologists, but also to the general public as a whole [1-4]. The prevalence of sexual reproduction suggests that there are major benefits provided by this mode of reproduction. The benefits, however, are not obvious. In many ways, asexual reproduction seems to be a better evolutionary strategy: only one parent is required, and all of the parent's genes are passed on to its progeny [5-12]. In a sexual population, the males are unable to produce offspring of their own and females only transfer half their genes to offspring, hence the theoretical problem of the 'two-fold cost of males.' Sexual reproduction must also go through obstacles that do not hinder asexual reproduction. Sexually reproducing organisms must spend a great deal of time and energy to find and attract mates. The peacock is a good example. The male must grow a large and intricate tail to attract mates; not only is producing the tail energy consuming, the peacock must also carry around its tail at all times, leaving it vulnerable to predators. Furthermore, copulation in sexually reproducing organisms leaves both organisms vulnerable to predation. Despite these major drawbacks to sexual reproduction, it is still a very prevalent form of reproduction in most living organisms.
