TLDR
The process of asexual reproduction by cloning with that by genetic crossover is found to be comparable as regards survival of a species, and also if a natural disaster is simulated.Abstract:
We perform Monte Carlo simulation using Penna's bit string model, and compare the process of asexual reproduction by cloning with that by genetic crossover. We find them to be comparable as regards survival of a species, and also if a natural disaster is simulated.read more

Why sex? monte carlo simulations of survival after catastrophes
TL;DR: It is shown that although both regimes present roughly the same survival rates, the diversity generated by SR is much larger, and can prevent the extinction of a population submitted to a natural disaster.

Computer simulations for biological aging and sexual reproduction
Dietrich Stauffer,Dietrich Stauffer,Paulo Murilo Castro de Oliveira,Suzana Moss de Oliveira,T. J. P. Penna,Jorge S. Sá Martins +5 more
TL;DR: In this article, the Penna model of biological aging is compared with alternative forms of reproduction as well as with models not involving aging, in order to check how sexual forms of life could have evolved and won over earlier asexual forms hundreds of million years ago.

Justification of sexual reproduction by modified Penna model of ageing
TL;DR: This work generalizes the standard Penna bit-string model of biological ageing and finds strong advantages or disadvantages of sexual reproduction compared to asexual cloning, depending on parameters.
Journal ArticleDOI
Why care about sex? Some Monte Carlo justification
TL;DR: Simulations of sexual reproduction based on the Redfield model may give sexual reproduction an advantage over asexual one, even if the male mutation rate is much higher than the female one, and if males do not get pregnant.

A Bit-String Model for Biological Aging
TL;DR: In this paper, a simple model for biological aging is presented and studied through computer simulations and they have found this model to reflect some features of real populations and have found that this model is more accurate than the one presented in this paper.

Viable offspring derived from fetal and adult mammalian cells
TL;DR: The birth of lambs from differentiated fetal and adult cells confirms that differentiation of that cell did not involve the irreversible modification of genetic material required for development to term and reinforces previous speculation that by inducing donor cells to become quiescent it will be possible to obtain normal development from a wide variety of differentiated cells.

Monte Carlo simulations of sexual reproduction
TL;DR: Modifying the Redfield model of sexual reproduction and the Penna model of biological aging, reproduction with and without recombination in age-structured populations is compared and sexual reproduction to be preferred to asexual one.

Can males contribute to the genetic improvement of a species
TL;DR: Using Monte Carlo simulations of age-structured populations, through the Penna model, it is shown that sexual reproduction with male competition can produce better results than meiotic parthenogenesis, which agrees with the strong evidence that nature chose sexual reproduction instead of partenogenesis for most of the higher species.
