Understanding the Biases of Generalised Recombination
In this paper we propose, model theoretically and study a general notion of recombination for fixed-length strings where homologous recombination, inversion, gene duplication, gene deletion, diploidy and more are just special cases. The analysis of the model reveals that the notion of schema emerges naturally from the model’s equations. The study provides a variety of fixed points for the case ...
متن کاملGenetic recombination in Micromonospora.
Biochemical mutants were obtained from Micromonospora chalcea, M. purpurea, and M. echinospora by using ultraviolet radiation or nitrosoguanidine. Crosses carried out between complementary nutritional mutants of the same species showed positive genetic interaction. Data are reported which indicate that the interaction between the crossed strains is due to genetic recombination. No evidence for ...
متن کاملMechanisms and impact of genetic recombination in the evolution of Streptococcus pneumoniae
Streptococcus pneumoniae (the pneumococcus) is a highly recombinogenic bacterium responsible for a high burden of human disease globally. Genetic recombination, a process in which exogenous DNA is acquired and incorporated into its genome, is a key evolutionary mechanism employed by the pneumococcus to rapidly adapt to selective pressures. The rate at which the pneumococcus acquires genetic var...
متن کاملGenetic recombination in plants.
Meiotic recombination generates novel allelic arrays on chromosomes. Recent experiments have revealed an extraordinarily nonrandom distribution of recombination breakpoints along the lengths of plant chromosomes; for example, recombination breakpoints often resolve within genic sequences, and thereby generate novel alleles. The mechanism by which recombination breakpoints are determined is an a...
متن کاملGenetic Set Recombination
The application of genetic algorithms to optimisation problems for which the solution is a set or multiset (bag) is considered. A previous extension of schema analysis, known as forma analysis, is further developed and used to construct principled representations and operators for problems in this class. The extensions to forma analysis include the introduction of genes whose values cannot be a...
