The Pros and Cons of Asexual Reproduction.

In science:

Most animal species use sexual reproduction to produce offspring, while a minority of species reproduce asexually by producing clones of the mother.
A Testing Framework for P Systems
Moreover, asexual populations composed by only females can reproduce twice as fast in each generation than sexual populations, because there is no need to produce males for ongoing reproduction.
A Testing Framework for P Systems
Asexual reproduction has only been described in less than 0.1% of vertebrate species.
A Testing Framework for P Systems
The rules controlling the evolution of the population are reproduction rules, either sexual reproduction rules or asexual, and death rules.
A Testing Framework for P Systems
We consider only haploid models with asexual reproduction, as is appropriate for macromolecules.
Biological Evolution and Statistical Physics
In this model, sexual individuals produce only half as many offspring as asexual individuals; mutation causes the switching between the two modes of reproduction.
Biological Evolution and Statistical Physics
The parasite genome is characterized by k binary loci, and the host genome by nk binary loci, with k loci for each parasite, and by an additional locus determining whether reproduction is sexual or asexual.
Biological Evolution and Statistical Physics
This Darwinian preselection of the fittest sperm cell does not exist for asexual reproduction and may justify the existence of men.
The Penna Model of Biological Aging
Sexual, as opposed to asexual, reproduction allows a new way to escape the detrimental effects of bad mutations.
The Penna Model of Biological Aging
Now that the reader may have understood the complementarity principle, what are the consequences of this possible survival strategy via complementarity? Also, complementarity is an advantage of sexual reproduction compared to the asexual haploid case where complementarity is impossible.
Review of haplotype complementarity under mutational pressure
In their approach they apply an asexual reproduction scheme, which means the offspring are only produced by one parent – not unlike bacteria – and not by two parents as used in a traditional GA.
Fitting of dust spectra with genetic algorithms - I. Perspectives & Limitations
In addition they observed that the strength of epistatic interactions is weaker in sexual organisms than in asexual ones and that the reproductive mode has a significant effect on the evolution of the genetic architecture.
The Emergence of Modularity in Biological Systems
Conversely, in slowly changing environments, asexual reproduction evolved to be predominant in most populations and sexual and asexual populations are equally fit on average.
The Emergence of Modularity in Biological Systems
We can interpret this new mutation as a point mutation (if we are considering asexual reproduction) or a recombination of the parent’s genome in sexual reproduction.
