ARP: asexual reproduction programming
Connection Science, 2021 Recently meta-heuristic techniques have attracted more attention. Algorithms based on Bio-inspired problems are among the most popular techniques of this field. In meta-heuristic algorithms, Genetic algorithm is one of the most useful. GA uses chromosome

Simulated emergence of cyclic sexual-asexual reproduction [PDF]
Physica A: Statistical Mechanics and its Applications, 2001 Motivated by the cyclic pattern of reproductive regimes observed in some species of green flies (``{\it aphids}''), we simulate the evolution of a population enduring harsh seasonal conditions for survival.

Thelytokous parthenogenesis in the fungus-gardening ant Mycocepurus smithii (Hymenoptera: Formicidae). [PDF]
PLoS ONE, 2009 The general prevalence of sexual reproduction over asexual reproduction among organisms testifies to the evolutionary benefits of recombination, such as accelerated adaptation to changing environments and elimination of deleterious mutations.

Transgenerational effects and temperature variation alter life history traits of the moon jellyfish
Frontiers in Marine Science, 2022 Understanding the life history strategy of organisms is key to predicting their population dynamics. The population of scyphozoan jellyfish has displayed an increasing trend in recent decades, yet its life history strategy is not fully understood.

Sexual versus Asexual Reproduction: Distinct Outcomes in Relative Abundance of Parthenogenetic Mealybugs following Recent Colonization. [PDF]
PLoS ONE, 2016 Asexual reproduction, including parthenogenesis in which embryos develop within a female without fertilization, is assumed to confer advantages over sexual reproduction, which includes a "cost of males." Sexual reproduction largely predominates in ...

Density, parasitism, and sexual reproduction are strongly correlated in lake Daphnia populations
Ecology and Evolution, 2021 Many organisms can reproduce both asexually and sexually. For cyclical parthenogens, periods of asexual reproduction are punctuated by bouts of sexual reproduction, and the shift from asexual to sexual reproduction has large impacts on fitness and ...

Scientific Reports, 2021 Asexual vertebrates are rare and at risk of extinction due to their restricted adaptability through the loss of genetic recombination. We explore the mechanisms behind the generation and maintenance of genetic diversity in triploid asexual (gynogenetic ...

Detection of Gene Flow from Sexual to Asexual Lineages in Thrips tabaci (Thysanoptera: Thripidae). [PDF]
PLoS ONE, 2015 Populations of Thrips tabaci are known to have two sympatric but genetically isolated reproductive modes, arrhenotoky (sexual reproduction) and thelytoky (asexual reproduction).

Scaling in a continuous time model for biological aging [PDF]
, 2000 In this paper we consider a generalization to the asexual version of the Penna model for biological aging, where we take a continuous time limit.
